Error code format
When an error is encountered during API access, the corresponding error code and information will be returned to identify and address the issue. If a request error occurs, detailed error information is provided within the Response Body, formatted as follows:
| Parameter name | Types | Description |
|---|---|---|
| code | String | Specify the exact error type. |
| message | String | Provide a detailed description of the error. |
| requestId | String | The requestId that caused the error. |
For example:
Plain Text
1{
2 "code":"IllegalRequestUrl",
3 "message":"The requested url belongs to domain which is not under acceleration",
4 "requestId":" 81d0b05f-5ad4-1f22-8068-d5c9de60a1d7"
