1# Custom Node Error Codes 2 3> **NOTE** 4> 5> This topic describes only module-specific error codes. For details about universal error codes, see [Universal Error Codes](../errorcode-universal.md). 6 7## 100021 FrameNode Not Modifiable 8 9**Error Message** 10 11The FrameNode is not modifiable. 12 13**Description** 14 15This error code is reported when the current FrameNode is unmodifiable, preventing the requested operation, for example, setting properties, adding or removing child nodes, or binding controllers. 16 17**Possible Causes** 18 19An attempt is made to modify a declarative node. 20 21**Solution** 22 23Avoid modifying unmodifiable nodes. Use try-catch to handle errors and prevent impact on other logic. 24 25## 100022 Cross-Language Attribute Configuration Not Supported 26 27**Error Message** 28 29The FrameNode cannot be set whether to support cross-language common attribute setting. 30 31**Description** 32 33This error code is reported when the target FrameNode does not support cross-language attribute configuration. 34 35**Possible Causes** 36 37An attempt is made to adjust the cross-language attribute permission of the target FrameNode. 38 39**Solution** 40 41NA 42 43## 100023 Parameter Error 44 45**Error Message** 46 47Parameter error. Possible causes: 1. The component type of the node is incorrect. 2. The node is null or undefined. 3. The controller is null or undefined. 48 49**Description** 50 51This error code is reported when the parameters passed to the API are incorrect. 52 53**Possible Causes** 54 551. The component type of the provided node is incorrect. 562. The provided node is null or undefined. 573. The provided controller is null or undefined. 58 59**Solution** 60 61Adjust the passed parameter values or perform pre-checks. 62 63## 106103 Operation Not Allowed on Nodes Created by ArkTS 64 65**Error Message** 66 67The corresponding operation does not support nodes created by ArkTS. 68 69**Description** 70 71This error code is reported when the operation does not support nodes created by ArkTS. 72 73**Possible Causes** 74 75The current operation is incompatible with nodes created by ArkTS. 76 77**Solution** 78 79Pass nodes not created by ArkTS. 80 81## 106203 Passed Node Not Mounted to Component Tree 82 83**Error Message** 84 85**Description** 86 87This error code is reported when the passed node is not mounted to the component tree. 88 89**Possible Causes** 90 91The passed node is not mounted to the component tree when the API is called. 92 93**Solution** 94 95Adjust the API call timing to ensure the node is mounted to the component tree. 96
