post-response-success

Every POST operation must have a successful response code (2XX or 3XX).

Why did this violation appear?

There is a POST Operation response in your specification that has not defined a success response code.

What is this rule checking for?

Every POST Operation response is checked for the inclusion of at least one success response code.

A bad example

"/pet":
  post:
    responses:
      '404':
        description: New pet was added, great job.

A good example

"/pet":
  post:
    operationId: createNewPet
    responses:
      '200':
        description: New pet added, great job. 

How do I fix this violation?

Every single POST Operation should have at least one success response code.
