Django channels 'No application configured for scope type 'websocket''

Question

I am trying to implement a chat with Django and channels according to this tutorial (http://channels.readthedocs.io/en/latest/tutorial/part_2.html). I add channels and a chat app to installed apps. I make the following routings for a project:

# mysite/routing.py
from channels.routing import ProtocolTypeRouter

application = ProtocolTypeRouter({
    # (http->django views is added by default)
})

Basically, I did exactly the steps from the tutorial. But after runserver I am still getting ValueError: No application configured for scope type 'websocket', after going to a specific chat room. Can please someone help me?

You updated your settings file?

You appear to be missing the websocket key. The tutorial says to add following imports and add the websocket key in mysite/routing.py.

from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
import chat.routing

application = ProtocolTypeRouter({
    # (http->django views is added by default)
    'websocket': AuthMiddlewareStack(
        URLRouter(
            chat.routing.websocket_urlpatterns
        )
    ),
})
