This prevents clients from accidentally creating duplicate commitments. 189 190The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000). 191 192Returns: 193 An object of the form: 194 195 { # Represents an Operation resource. 196 # 197 # You can use an operation resource to manage asynchronous API requests.

This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. 261 262Currently, only sorting by name or creationTimestamp desc is supported. 263 maxResults: integer, The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests.

Set pageToken to the nextPageToken returned by a previous list request to get the next page of results. 265 filter: string, A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either =, !=, >, or <. 266 267For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance. 268 269You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. 270 271To filter on multiple expressions, provide each separate expression within parentheses. For example, (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake"). By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly.
