Error Code
If an error occurs during API calling, no result is returned. You can locate the cause of an error using the error code of each API. When an API call fails, HTTPS status code 4xx or 5xx is returned. The returned message body contains a specific error code and error message. If you fail to locate the cause of the error, contact HUAWEI CLOUD customer service and provide the error code for troubleshooting.
Format of an Error Response Body
If an error occurs during API calling, an error code and a message will be displayed. The following shows an error response body.
{
"error_msg": "The format of message is error",
"error_code": "AS.0001"
} In the response body, error_code is an error code, and error_msg provides information about the error.
