API documentation for Export Service is only documenting 200 success responses and missing all error codes. Implementing automation and custom client against this API without error code would require extra time for each individual developer as they will have to try and get an error code to determine the API behavior. This is not the experience we want to provide. All expected error code and a description should be provided in the documentation.
