A generic error message
data class CommonErrorMessage( val why: String, val errorCode: String?, )
UCloud uses HTTP status code for all error messages. In addition and if possible, UCloud will include a message using a common format. Note that this is not guaranteed to be included in case of a failure somewhere else in the network stack. For example, UCloud’s load balancer might not be able to contact the backend at all. In such a case UCloud will not include a more detailed error message.
