'AsgiRequest' object has no attribute 'register'

Hello,

After following the installation instructions, and using the example in the README with django==2.2.1 and django-channels-graphql-ws==0.2.0 on Python 3.7.3, when making any subscription operation:

subscription {
  mySubscription {event}
}

{
  "errors": [
    {
      "message": "'AsgiRequest' object has no attribute 'register'"
    }
  ],
  "data": null
}

Traceback:

AttributeError: 'AsgiRequest' object has no attribute 'register'

While I can see where the ‘register’ attribute is needed: https://github.com/datadvance/DjangoChannelsGraphqlWs/blob/master/channels_graphql_ws/graphql_ws.py#L425, I can’t see what could have caused it to be deleted from the context before going through Subscription._subscribe.

Do you have any idea what could lead to that situtation, and how to fix it?

Hey @rigelk ,

AsgiRequest is used in channels.http.AsgiHandler. If a http argument is not provided in channels.routing.ProtocolTypeRouter, it will default to the Django view system’s ASGI interface, channels.http.AsgiHandler.

So AsgiHandler is done specifically to work with ordinary normal Django views by default. In our example we don’t provide http, we provide websocket argument for websocket connections:

application = channels.routing.ProtocolTypeRouter(
    {
        "websocket": channels.routing.URLRouter(
            [django.urls.path("graphql/", MyGraphqlWsConsumer)]
        )
    }
)

In this way our GraphqlWsConsumer from example does not use AsgiRequest and AsgiHandler for HTTP, because AsyncJsonWebsocketConsumer doesn’t do that. The only HTTP path (after which AsgiRequest will be created) in our example is the path to graphiql, but it is not connected to GraphqlWsConsumer:

urlpatterns = [django.urls.path("", graphiql)]

Could you show how you configure ProtocolTypeRouter and urlpatterns? What kind of requests do you send to the server via HTTP? This could help reproduce this problem.

@Thibaut-Fatus would you mind sharing a bit how you implemented this in a react app
