Args:
  serviceName: string, The name of the service.  See the [overview](/service-management/overview)
for naming requirements.  For example: `example.googleapis.com`. (required)
  body: object, The request body. (required)
    The object takes the form of:

{ # `Service` is the root object of Google service configuration schema. It
    # describes basic information about a service, such as the name and the
    # title, and delegates other aspects to sub-sections. Each sub-section is
    # either a proto message or a repeated proto message that configures a
    # specific aspect, such as auth. See each proto message definition for details.

          # In general, not only fields but also field paths can be referenced
          # from a path pattern. Fields mapped to the path pattern cannot be
          # repeated and must have a primitive (non-message) type.
          #
          # Any fields in the request message which are not bound by the path

          #     service Messaging {
          #       rpc GetMessage(GetMessageRequest) returns (Message) {

          #     }
          #
          #
          # This enables a HTTP JSON to RPC mapping as below:

          # HTTP | RPC
          # -----|-----
          # `GET /v1/messages/123456?revision=2&sub.subfield=foo` | `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: "foo"))`
          #
          # Note that fields which are mapped to HTTP parameters must have a
          # primitive type or a repeated primitive type. Message types are not
          # allowed. In the case of a repeated type, the parameter can be
          # repeated in the URL, as in `...?param=A&param=B`.
          #
          # For HTTP method kinds which allow a request body, the `body` field
          # specifies the mapping. Consider a REST update method on the

          #     message UpdateMessageRequest {
          #       string message_id = 1; // mapped to the URL
          #       Message message = 2;   // mapped to the body
          #     }
          #
          #
          # The following HTTP JSON to RPC mapping is enabled, where the
          # representation of the JSON in the request body is determined by
          # protos JSON encoding:
          #
          # HTTP | RPC
          # -----|-----
          # `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" message { text: "Hi!" })`
          #
          # The special name `*` can be used in the body mapping to define that
          # every field not bound by the path template should be mapped to the
          # request body.  This enables the following alternative definition of
          # the update method:
          #
          #     service Messaging {
          #       rpc UpdateMessage(Message) returns (Message) {
          #         option (google.api.http) = {
          #           put: "/v1/messages/{message_id}"
          #           body: "*"
          #         };
          #       }
          #     }
          #     message Message {
          #       string message_id = 1;
          #       string text = 2;
          #     }
          #
          #
          # The following HTTP JSON to RPC mapping is enabled:
          #
          # HTTP | RPC
          # -----|-----
          # `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" text: "Hi!")`
          #
          # Note that when using `*` in the body mapping, it is not possible to
          # have HTTP parameters, as all fields not bound by the path end in
          # the body. This makes this option more rarely used in practice of
          # defining REST APIs. The common usage of `*` is in custom methods
          # which don't use the URL at all for transferring data.
          #
          # It is possible to define multiple HTTP methods for one RPC by using
          # the `additional_bindings` option. Example:
          #
          #     service Messaging {
          #       rpc GetMessage(GetMessageRequest) returns (Message) {
          #         option (google.api.http) = {
          #           get: "/v1/messages/{message_id}"
          #           additional_bindings {
          #             get: "/v1/users/{user_id}/messages/{message_id}"
          #           }
          #         };
          #       }
          #     }
          #     message GetMessageRequest {
          #       string message_id = 1;
          #       string user_id = 2;
          #     }
          #
          #
          # This enables the following two alternative HTTP JSON to RPC
          # mappings:
          #
          # HTTP | RPC
          # -----|-----
          # `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
          # `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: "123456")`
          #
          # # Rules for HTTP mapping
          #
          # The rules for mapping HTTP path, query parameters, and body fields
          # to the request message are as follows:
          #
          # 1. The `body` field specifies either `*` or a field path, or is
          #    omitted. If omitted, it assumes there is no HTTP body.
          # 2. Leaf fields (recursive expansion of nested messages in the
          #    request) can be classified into three types:
          #     (a) Matched in the URL template.
          #     (b) Covered by body (if body is `*`, everything except (a) fields;
          #         else everything under the body field)
          #     (c) All other fields.
          # 3. URL query parameters found in the HTTP request are mapped to (c) fields.
          # 4. Any body sent with an HTTP request can contain only (b) fields.
          #
          # The syntax of the path template is as follows:
          #
          #     Template = "/" Segments [ Verb ] ;
          #     Segments = Segment { "/" Segment } ;
          #     Segment  = "*" | "**" | LITERAL | Variable ;
          #     Variable = "{" FieldPath [ "=" Segments ] "}" ;
          #     FieldPath = IDENT { "." IDENT } ;
          #     Verb     = ":" LITERAL ;
          #
          # The syntax `*` matches a single path segment. It follows the semantics of
          # [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
          # Expansion.
          #
          # The syntax `**` matches zero or more path segments. It follows the semantics
          # of [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.3 Reserved
          # Expansion. NOTE: it must be the last segment in the path except the Verb.
          #
          # The syntax `LITERAL` matches literal text in the URL path.
          #
          # The syntax `Variable` matches the entire path as specified by its template;
          # this nested template must not contain further variables. If a variable
          # matches a single path segment, its template may be omitted, e.g. `{var}`
          # is equivalent to `{var=*}`.
          #
          # NOTE: the field paths in variables and in the `body` must not refer to
          # repeated fields or map fields.
          #
          # Use CustomHttpPattern to specify any HTTP method that is not included in the
          # `pattern` field, such as HEAD, or "*" to leave the HTTP method unspecified for
          # a given URL path rule. The wild-card rule is useful for services that provide

            # message, as in the example below which describes a REST GET
            # operation on a resource collection of messages:
            #
            #
            #     service Messaging {
            #       rpc GetMessage(GetMessageRequest) returns (Message) {
            #         option (google.api.http).get = "/v1/messages/{message_id}/{sub.subfield}";
            #       }
            #     }
            #     message GetMessageRequest {
            #       message SubMessage {
            #         string subfield = 1;
            #       }
            #       string message_id = 1; // mapped to the URL
            #       SubMessage sub = 2;    // `sub.subfield` is url-mapped
            #     }
            #     message Message {
            #       string text = 1; // content of the resource
            #     }
            #
            # The same http annotation can alternatively be expressed inside the
            # `GRPC API Configuration` YAML file.
            #
            #     http:
            #       rules:
            #         - selector: <proto_package_name>.Messaging.GetMessage
            #           get: /v1/messages/{message_id}/{sub.subfield}
            #
            # This definition enables an automatic, bidrectional mapping of HTTP
            # JSON to RPC. Example:
            #
            # HTTP | RPC
            # -----|-----
            # `GET /v1/messages/123456/foo`  | `GetMessage(message_id: "123456" sub: SubMessage(subfield: "foo"))`
            #
            # In general, not only fields but also field paths can be referenced
            # from a path pattern. Fields mapped to the path pattern cannot be
            # repeated and must have a primitive (non-message) type.
            #
            # Any fields in the request message which are not bound by the path
            # pattern automatically become (optional) HTTP query
            # parameters. Assume the following definition of the request message:
            #
            #
            #     service Messaging {
            #       rpc GetMessage(GetMessageRequest) returns (Message) {
            #         option (google.api.http).get = "/v1/messages/{message_id}";
            #       }
            #     }
            #     message GetMessageRequest {
            #       message SubMessage {
            #         string subfield = 1;
            #       }
            #       string message_id = 1; // mapped to the URL
            #       int64 revision = 2;    // becomes a parameter
            #       SubMessage sub = 3;    // `sub.subfield` becomes a parameter
            #     }
            #
            #
            # This enables a HTTP JSON to RPC mapping as below:
            #
            # HTTP | RPC
            # -----|-----
            # `GET /v1/messages/123456?revision=2&sub.subfield=foo` | `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: "foo"))`
            #
            # Note that fields which are mapped to HTTP parameters must have a
            # primitive type or a repeated primitive type. Message types are not
            # allowed. In the case of a repeated type, the parameter can be
            # repeated in the URL, as in `...?param=A&param=B`.
            #
            # For HTTP method kinds which allow a request body, the `body` field
            # specifies the mapping. Consider a REST update method on the
            # message resource collection:
            #
            #
            #     service Messaging {
            #       rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
            #         option (google.api.http) = {
            #           put: "/v1/messages/{message_id}"
            #           body: "message"
            #         };
            #       }
            #     }
            #     message UpdateMessageRequest {
            #       string message_id = 1; // mapped to the URL
            #       Message message = 2;   // mapped to the body
            #     }
            #
            #
            # The following HTTP JSON to RPC mapping is enabled, where the
            # representation of the JSON in the request body is determined by
            # protos JSON encoding:
            #
            # HTTP | RPC
            # -----|-----
            # `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" message { text: "Hi!" })`
            #
            # The special name `*` can be used in the body mapping to define that
            # every field not bound by the path template should be mapped to the
            # request body.  This enables the following alternative definition of
            # the update method:
            #
            #     service Messaging {
            #       rpc UpdateMessage(Message) returns (Message) {
            #         option (google.api.http) = {
            #           put: "/v1/messages/{message_id}"
            #           body: "*"
            #         };
            #       }
            #     }
            #     message Message {
            #       string message_id = 1;
            #       string text = 2;
            #     }
            #
            #
            # The following HTTP JSON to RPC mapping is enabled:
            #
            # HTTP | RPC
            # -----|-----
            # `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" text: "Hi!")`
            #
            # Note that when using `*` in the body mapping, it is not possible to
            # have HTTP parameters, as all fields not bound by the path end in
            # the body. This makes this option more rarely used in practice of
            # defining REST APIs. The common usage of `*` is in custom methods
            # which don't use the URL at all for transferring data.
            #
            # It is possible to define multiple HTTP methods for one RPC by using
            # the `additional_bindings` option. Example:
            #
            #     service Messaging {
            #       rpc GetMessage(GetMessageRequest) returns (Message) {
            #         option (google.api.http) = {
            #           get: "/v1/messages/{message_id}"
            #           additional_bindings {
            #             get: "/v1/users/{user_id}/messages/{message_id}"
            #           }
            #         };
            #       }
            #     }
            #     message GetMessageRequest {
            #       string message_id = 1;
            #       string user_id = 2;
            #     }
            #
            #
            # This enables the following two alternative HTTP JSON to RPC
            # mappings:
            #
            # HTTP | RPC
            # -----|-----
            # `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
            # `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: "123456")`
            #
            # # Rules for HTTP mapping
            #
            # The rules for mapping HTTP path, query parameters, and body fields
            # to the request message are as follows:
            #
            # 1. The `body` field specifies either `*` or a field path, or is
            #    omitted. If omitted, it assumes there is no HTTP body.
            # 2. Leaf fields (recursive expansion of nested messages in the
            #    request) can be classified into three types:
            #     (a) Matched in the URL template.
            #     (b) Covered by body (if body is `*`, everything except (a) fields;
            #         else everything under the body field)
            #     (c) All other fields.
            # 3. URL query parameters found in the HTTP request are mapped to (c) fields.
            # 4. Any body sent with an HTTP request can contain only (b) fields.
            #
            # The syntax of the path template is as follows:
            #
            #     Template = "/" Segments [ Verb ] ;
            #     Segments = Segment { "/" Segment } ;
            #     Segment  = "*" | "**" | LITERAL | Variable ;
            #     Variable = "{" FieldPath [ "=" Segments ] "}" ;
            #     FieldPath = IDENT { "." IDENT } ;
            #     Verb     = ":" LITERAL ;
            #
            # The syntax `*` matches a single path segment. It follows the semantics of
            # [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
            # Expansion.
            #
            # The syntax `**` matches zero or more path segments. It follows the semantics
            # of [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.3 Reserved
            # Expansion. NOTE: it must be the last segment in the path except the Verb.
            #
            # The syntax `LITERAL` matches literal text in the URL path.
            #
            # The syntax `Variable` matches the entire path as specified by its template;
            # this nested template must not contain further variables. If a variable
            # matches a single path segment, its template may be omitted, e.g. `{var}`
            # is equivalent to `{var=*}`.
            #
            # NOTE: the field paths in variables and in the `body` must not refer to
            # repeated fields or map fields.
            #
            # Use CustomHttpPattern to specify any HTTP method that is not included in the
            # `pattern` field, such as HEAD, or "*" to leave the HTTP method unspecified for
            # a given URL path rule. The wild-card rule is useful for services that provide

              #     rpc AddressesAggregatedList(AddressesAggregatedListRequest)

    "http": { # Defines the HTTP configuration for a service. It contains a list of # HTTP configuration.
        # HttpRule, each specifying the mapping of an RPC method
        # to one or more HTTP REST API methods.
      "rules": [ # A list of HTTP configuration rules that apply to individual API methods.

        { # `HttpRule` defines the mapping of an RPC method to one or more HTTP
            # REST APIs.  The mapping determines what portions of the request
            # message are populated from the path, query parameters, or body of
            # the HTTP request.  The mapping is typically specified as an
            # `google.api.http` annotation, see "google/api/annotations.proto"
            # for details.
            #
            # The mapping consists of a field specifying the path template and
            # method kind.  The path template can refer to fields in the request
            # message, as in the example below which describes a REST GET
            # operation on a resource collection of messages:
            #

            #     service Messaging {
            #       rpc GetMessage(GetMessageRequest) returns (Message) {
            #         option (google.api.http).get = "/v1/messages/{message_id}/{sub.subfield}";
            #       }

            #       string message_id = 1; // mapped to the URL
            #       SubMessage sub = 2;    // `sub.subfield` is url-mapped

            #           get: /v1/messages/{message_id}/{sub.subfield}
            #
            # This definition enables an automatic, bidrectional mapping of HTTP
            # JSON to RPC. Example:
            #
            # HTTP | RPC
            # -----|-----
            # `GET /v1/messages/123456/foo`  | `GetMessage(message_id: "123456" sub: SubMessage(subfield: "foo"))`
            #
            # In general, not only fields but also field paths can be referenced
            # from a path pattern. Fields mapped to the path pattern cannot be
            # repeated and must have a primitive (non-message) type.
            #
            # Any fields in the request message which are not bound by the path
            # pattern automatically become (optional) HTTP query
            # parameters. Assume the following definition of the request message:
            #
            #
            #     service Messaging {
            #       rpc GetMessage(GetMessageRequest) returns (Message) {
            #         option (google.api.http).get = "/v1/messages/{message_id}";
            #       }
            #     }
            #     message GetMessageRequest {
            #       message SubMessage {
            #         string subfield = 1;
            #       }
            #       string message_id = 1; // mapped to the URL
            #       int64 revision = 2;    // becomes a parameter
            #       SubMessage sub = 3;    // `sub.subfield` becomes a parameter
            #     }
            #
            #
            # This enables a HTTP JSON to RPC mapping as below:
            #
            # HTTP | RPC
            # -----|-----
            # `GET /v1/messages/123456?revision=2&sub.subfield=foo` | `GetMessage(message_id: "123456" revision: 2 sub: SubMessage(subfield: "foo"))`
            #
            # Note that fields which are mapped to HTTP parameters must have a
            # primitive type or a repeated primitive type. Message types are not
            # allowed. In the case of a repeated type, the parameter can be
            # repeated in the URL, as in `...?param=A&param=B`.
            #
            # For HTTP method kinds which allow a request body, the `body` field
            # specifies the mapping. Consider a REST update method on the
            # message resource collection:
            #
            #
            #     service Messaging {
            #       rpc UpdateMessage(UpdateMessageRequest) returns (Message) {
            #         option (google.api.http) = {
            #           put: "/v1/messages/{message_id}"
            #           body: "message"
            #         };
            #       }
            #     }
            #     message UpdateMessageRequest {
            #       string message_id = 1; // mapped to the URL
            #       Message message = 2;   // mapped to the body
            #     }
            #
            #
            # The following HTTP JSON to RPC mapping is enabled, where the
            # representation of the JSON in the request body is determined by
            # protos JSON encoding:
            #
            # HTTP | RPC
            # -----|-----
            # `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" message { text: "Hi!" })`
            #
            # The special name `*` can be used in the body mapping to define that
            # every field not bound by the path template should be mapped to the
            # request body.  This enables the following alternative definition of
            # the update method:
            #
            #     service Messaging {
            #       rpc UpdateMessage(Message) returns (Message) {
            #         option (google.api.http) = {
            #           put: "/v1/messages/{message_id}"
            #           body: "*"
            #         };
            #       }
            #     }
            #     message Message {
            #       string message_id = 1;
            #       string text = 2;
            #     }
            #
            #
            # The following HTTP JSON to RPC mapping is enabled:
            #
            # HTTP | RPC
            # -----|-----
            # `PUT /v1/messages/123456 { "text": "Hi!" }` | `UpdateMessage(message_id: "123456" text: "Hi!")`
            #
            # Note that when using `*` in the body mapping, it is not possible to
            # have HTTP parameters, as all fields not bound by the path end in
            # the body. This makes this option more rarely used in practice of
            # defining REST APIs. The common usage of `*` is in custom methods
            # which don't use the URL at all for transferring data.
            #
            # It is possible to define multiple HTTP methods for one RPC by using
            # the `additional_bindings` option. Example:
            #
            #     service Messaging {
            #       rpc GetMessage(GetMessageRequest) returns (Message) {
            #         option (google.api.http) = {
            #           get: "/v1/messages/{message_id}"
            #           additional_bindings {
            #             get: "/v1/users/{user_id}/messages/{message_id}"
            #           }
            #         };
            #       }
            #     }
            #     message GetMessageRequest {
            #       string message_id = 1;
            #       string user_id = 2;
            #     }
            #
            #
            # This enables the following two alternative HTTP JSON to RPC
            # mappings:
            #
            # HTTP | RPC
            # -----|-----
            # `GET /v1/messages/123456` | `GetMessage(message_id: "123456")`
            # `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: "123456")`
            #
            # # Rules for HTTP mapping
            #
            # The rules for mapping HTTP path, query parameters, and body fields
            # to the request message are as follows:
            #
            # 1. The `body` field specifies either `*` or a field path, or is
            #    omitted. If omitted, it assumes there is no HTTP body.
            # 2. Leaf fields (recursive expansion of nested messages in the
            #    request) can be classified into three types:
            #     (a) Matched in the URL template.
            #     (b) Covered by body (if body is `*`, everything except (a) fields;
            #         else everything under the body field)
            #     (c) All other fields.
            # 3. URL query parameters found in the HTTP request are mapped to (c) fields.
            # 4. Any body sent with an HTTP request can contain only (b) fields.
            #
            # The syntax of the path template is as follows:
            #
            #     Template = "/" Segments [ Verb ] ;
            #     Segments = Segment { "/" Segment } ;
            #     Segment  = "*" | "**" | LITERAL | Variable ;
            #     Variable = "{" FieldPath [ "=" Segments ] "}" ;
            #     FieldPath = IDENT { "." IDENT } ;
            #     Verb     = ":" LITERAL ;
            #
            # The syntax `*` matches a single path segment. It follows the semantics of
            # [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
            # Expansion.
            #
            # The syntax `**` matches zero or more path segments. It follows the semantics
            # of [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.3 Reserved
            # Expansion. NOTE: it must be the last segment in the path except the Verb.
            #
            # The syntax `LITERAL` matches literal text in the URL path.
            #
            # The syntax `Variable` matches the entire path as specified by its template;
            # this nested template must not contain further variables. If a variable
            # matches a single path segment, its template may be omitted, e.g. `{var}`
            # is equivalent to `{var=*}`.
            #
            # NOTE: the field paths in variables and in the `body` must not refer to
            # repeated fields or map fields.
            #
            # Use CustomHttpPattern to specify any HTTP method that is not included in the
            # `pattern` field, such as HEAD, or "*" to leave the HTTP method unspecified for
            # a given URL path rule. The wild-card rule is useful for services that provide

              # `*` for mapping all fields not captured by the path pattern to the HTTP

              #     rpc AddressesAggregatedList(AddressesAggregatedListRequest)

                #
                # The special name `*` can be used in the body mapping to define that

                # Note that when using `*` in the body mapping, it is not possible to
                # have HTTP parameters, as all fields not bound by the path end in
                # the body. This makes this option more rarely used in practice of
                # defining REST APIs. The common usage of `*` is in custom methods
                # which don't use the URL at all for transferring data.
                #
                # It is possible to define multiple HTTP methods for one RPC by using
                # the `additional_bindings` option. Example:
                #

                #
                # This enables the following two alternative HTTP JSON to RPC

                # `GET /v1/users/me/messages/123456` | `GetMessage(user_id: "me" message_id: "123456")`
                #
                # # Rules for HTTP mapping
                #
                # The rules for mapping HTTP path, query parameters, and body fields
                # to the request message are as follows:
                #
                # 1. The `body` field specifies either `*` or a field path, or is
                #    omitted. If omitted, it assumes there is no HTTP body.
                # 2. Leaf fields (recursive expansion of nested messages in the
                #    request) can be classified into three types:
                #     (a) Matched in the URL template.
                #     (b) Covered by body (if body is `*`, everything except (a) fields;
                #         else everything under the body field)
                #     (c) All other fields.
                # 3. URL query parameters found in the HTTP request are mapped to (c) fields.
                # 4. Any body sent with an HTTP request can contain only (b) fields.
                #
                # The syntax of the path template is as follows:
                #
                #     Template = "/" Segments [ Verb ] ;
                #     Segments = Segment { "/" Segment } ;
                #     Segment  = "*" | "**" | LITERAL | Variable ;
                #     Variable = "{" FieldPath [ "=" Segments ] "}" ;
                #     FieldPath = IDENT { "." IDENT } ;
                #     Verb     = ":" LITERAL ;
                #
                # The syntax `*` matches a single path segment. It follows the semantics of
                # [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.2 Simple String
                # Expansion.
                #
                # The syntax `**` matches zero or more path segments. It follows the semantics
                # of [RFC 6570](https://tools.ietf.org/html/rfc6570) Section 3.2.3 Reserved
                # Expansion. NOTE: it must be the last segment in the path except the Verb.
                #
                # The syntax `LITERAL` matches literal text in the URL path.
                #

                # The grammar includes the dimensionless unit `1`, such as `1/s`.
                #
                # The grammar also includes these connectors:
                #
                # * `/`    division (as an infix operator, e.g. `1/s`).
                # * `.`    multiplication (as an infix operator, e.g. `GBy.d`)
                #
                # The grammar for a unit is as follows:
                #
                #     Expression = Component { "." Component } { "/" Component } ;
                #
                #     Component = [ PREFIX ] UNIT [ Annotation ]
                #               | Annotation
                #               | "1"

                #     Annotation = "{" NAME "}" ;
                #
                # Notes:
                #
                # * `Annotation` is just a comment if it follows a `UNIT` and is
                #    equivalent to `1` if it is used alone. For examples,
                #    `{requests}/s == 1/s`, `By{transmitted}/s == By/s`.
                # * `NAME` is a sequence of non-blank printable ASCII characters not
                #    containing '{' or '}'.

        # programming environments, including REST APIs and RPC APIs. It is used by
        # [gRPC](https://github.com/grpc). The error model is designed to be:
        #
        # - Simple to use and understand for most users
        # - Flexible enough to meet unexpected needs
        #
        # # Overview
        #
        # The `Status` message contains three pieces of data: error code, error message,
        # and error details. The error code should be an enum value of
        # google.rpc.Code, but it may accept additional error codes if needed.  The
        # error message should be a developer-facing English message that helps
        # developers *understand* and *resolve* the error. If a localized user-facing
        # error message is needed, put the localized message in the error details or
        # localize it in the client. The optional error details may contain arbitrary
        # information about the error. There is a predefined set of error detail types
        # in the package `google.rpc` that can be used for common error conditions.
        #
        # # Language mapping
        #
        # The `Status` message is the logical representation of the error model, but it
        # is not necessarily the actual wire format. When the `Status` message is
        # exposed in different client libraries and different wire protocols, it can be
        # mapped differently. For example, it will likely be mapped to some exceptions
        # in Java, but more likely mapped to some error codes in C.
        #
        # # Other uses
        #
        # The error model and the `Status` message can be used in a variety of
        # environments, either with or without APIs, to provide a
        # consistent developer experience across different environments.
        #
        # Example uses of this error model include:
        #
        # - Partial errors. If a service needs to return partial errors to the client,
        #     it may embed the `Status` in the normal response to indicate the partial
        #     errors.
        #
        # - Workflow errors. A typical workflow has multiple steps. Each step may
        #     have a `Status` message for error reporting.
        #
        # - Batch operations. If a client uses batch request and batch response, the
        #     `Status` message should be used directly inside batch response, one for
        #     each error sub-response.
        #
        # - Asynchronous operations. If an API call embeds asynchronous operation
        #     results in its response, the status of those operations should be
        #     represented directly using the `Status` message.
        #
        # - Logging. If some API errors are stored in logs, the message `Status` could
        #     be used directly after any stripping needed for security/privacy reasons.
      "message": "A String", # A developer-facing error message, which should be in English. Any
          # user-facing error message should be localized and sent in the

        # `Get`/`Create`/`Update`, the response should be the resource.  For other
