Validating and documenting a 204 No Content endpoint

What are you trying to achieve or the steps to reproduce ?

I’m trying to document my delete endpoint. It returns a statusCode of 204 No Content. I’m not sure how to document this endpoint and the response. If I leave the statusCode out in the validation, it won’t show up in /documentation. If I put 204: Joi.string().length(0) it fails validation.

What is the proper way to validate and document and endpoint which returns 204 No Content?

// handler
function (req, reply) {
  // ...
  return reply().code(204);
}

// Response validation
// ...
      response: {
        status: {
          204: ?
          404: schema.responseNotFound
        }
      }

Could you please review this PR #601

This will allow setting a No Content endpoint by just specifying:

      response: {
        status: {
          204: undefined
        }
      }

Using “204: Joi.only(null)” has started to produce invalid Swagger contracts; might have a regression somewhere.
