null arguments being passed to mutate as kwargs

[daynejones]

class UpdateThing(graphene.Mutation):
    class Arguments:
        guid = graphene.UUID(required=True)
        selector = graphene.String()
        note = graphene.String()

    Output = Thing

    def mutate(root, info, guid, **kwargs):
        print(kwargs)
        placement_rule = ThingAPI.update_thing(
            guid=guid,
            selector=selector,
            note=note,
        )
        return thing

Query:

mutation {
  updateThing(
    guid: "foo", selector: ".test") {
      note
  }
}

print(kwargs) prints the following:

{"guid": "foo", "selector": ".test", "note": None}

As a result, I have no idea whether note was omitted or if a null value was passed in. According to the docs, kwargs should contain only the arguments that were actually passed in. Hopefully I'm crazy and there's something I'm missing or some other canonical way of achieving what I want. Thanks for the help.

Would be fixed with: https://github.com/graphql-python/graphene/pull/1300

How are people getting around this? This impacts query filter arguments as well
