Re: Django Channels - core.py error

I've just had trouble with exactly the same error. In my case I was building from the tutorial ChatConsumer with my own XChatConsumer and I hadn't referenced it in the routing.py. As a result the tutorial async chat consumer was receiving a scope that did not contain a room_name in its url_route kwargs. Very obscure! I think the channel gets closed by an error and then this 500 error comes up rather than anything helpful for the original error.

Hi Simon,

Sorry to hear that you are having the same problem! Channels can be a blessing and a curse. I find it very finicky with very poor documentation & poor error handling. As for the fix: I had an AsyncWebsocketConsumer class in consumers.py within which I had a custom __init__ function. I believe I was setting the scope incorrectly within the init. I realized that I had no need to override/augment the init and removed it. The result was that the error disappeared. That was it for me. I have since updated to all the latest builds for the channels & redis infrastructure.

Hope that helps.

Cheers,

Nathan

Hi itsnate_b,

Would you mind elaborating on your fix?

I'm getting this exact error and I'm at a complete loss.   Everything works fine in local, but on my live server, after a couple of minutes/hours of working fine, I start getting this error in the logs.

Thanks!

Turns out there was an erroneous init function in the AsyncWebsocketConsumer class. Removing it fixed the issue.
