Unsuccessful response example

After an error is encountered in an interface call, no result data will be returned. The caller can locate the error cause according to the error code and Public error codes corresponding to each interface.

When an error occurs in a call, the HTTP request will return an HTTP status code of 4xx or 5xx. The returned message body contains the specific error code and error message. The message body also contains a globally unique RequestId and the requested HostId. If the caller cannot find the cause of the error, he can contact AliCloud customer service and provide the HostId and RequestId to help us solve the problem as quickly as possible.
