Suggested Fixes

  • Add an entry in the responses list for the default success response code of your operation/endpoint e.g. 200. If other success status codes and their definitions are well-known, add their entries too.
  • The successful response codes belong to the HTTP status code range of 2XX e.g. 200, 201, etc.
  • If all success responses possible for your operation share the same structure, you can define them once using the status code range 2XX instead of defining with an explicit code.
