Cannot manually represent a Response without setting a schema?

[insertjokehere]

Not sure if this is a bug, or if I'm just not reading the docs correctly:

I have a view that returns a '204 No Content' status, with a header that returns some relevant information, and no response body. I want to correctly represent this in my API documentation, so I'm doing something like this:

class MyView(APIView):
    @swagger_auto_schema(
        responses={
            "204": openapi.Response(
                description="Your request was accepted, perform status queries using the value of the X-Query-ID header for updates",
                 headers={
                     "X-Query-ID": {
                         "description": "The ID of the accepted query",
                         "type": openapi.TYPE_STRING
                     }
                 }
             )
         }
    )
    def post(self, request, ...):

However this fails with the following trace:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/site-packages/drf_yasg/openapi.py", line 99, in __getattr__
    return self[make_swagger_name(item)]
KeyError: 'schema'

During handling of the above exception, another exception occurred:

AttributeError: object of class Response has no attribute schema

It works if I set the schema kwarg on the Response (either with a serializer or a manually created Schema instance; setting it to no_body doesn't work). As far as I can tell I should be able to specify a Response without a Schema (I can if I set the value of the responses dict to a string)?

Yep. This looks like an oversight. Will fix.
