Example not working [similar to #177]

Using Ariadne==0.5.0 and Uvicorn==0.8.3, following the example on https://ariadnegraphql.org/docs/django-integration, where it is in a list called http_routes, and used in a ProtocalTypeRouter:

http_routes = []
http_routes.append(path("graphql/", GraphQL(schema, debug=True)))

router = ProtocolTypeRouter({
    "http": URLRouter(http_routes),
    "channel": ChannelNameRouter({
        "channelone": ChannelOneConsumer
    })
})

When Apollo-Federation calls this endpoint, I get:

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/site-packages/uvicorn/protocols/http/httptools_impl.py", line 368, in run_asgi

The comment https://github.com/mirumee/ariadne/issues/177#issuecomment-493950544 says that Ariadne should be using ASGI3, but uvicorn still shows to be using ASGI2? (uvicorn/middleware/asgi2.py). Btw I am using channels==2.2.0 What should I do to get around this?

I think you may be confusing two separate integrations, one for Django and one for Django Channels. You should only use one of them. Django Channels integration is currently broken as we’re waiting for an ASGI3 version of Channels.

Here’s a workaround ASGI2 compatibility class that you can use instead of ariadne.asgi.GraphQL if you want to use it:

from ariadne.asgi import GraphQL

class DjangoChannelsGraphQL(GraphQL):
    def __call__(self, scope) -> None:
        async def handle(receive, send):
            await super(DjangoChannelsGraphQL, self).__call__(scope, receive, send)
        return handle
