AttributeError: Type "execute_async" not found in the Schema.

Hi there, I am using graphene 2.1.8 with the tornado framework. I am trying to setup an async graphene mutation and it appears to not think the function exists on the graphene Schema class. My code is roughly setup like this:

graphql = graphene.Schema(query=Query, mutation=Mutations, subscription=Subscriptions)
async def query_async(self, query, queueLayer, variables, context):
        return await graphql.execute_async(query, variables=variables, context=context)

And I get this error:

AttributeError: Type "execute_async" not found in the Schema

EDIT: I tried setting up a very basic example of execute_async using the example in graphene/tests_asyncio/test_relay_mutation.py and it is still giving me a similar error.

@mariaines I ended up having to create a separate route that is completely async. It parses the incoming graphql request manually (yuck I know), runs the async tasks needed, stuffs the information in a middleware function and calls the original schema.execute() passing in the middleware. It’s a super hacky solution I know but the only one I could think of without avoiding graphene completely.

@uSpike whelp that will do it! Thanks so much for the info.
