Not able to see tracebacks

Hi,

I’m trying to upgrade my project to channels 2 but I’ve noticed a weird behavior when an exception is raised on a consumer I’m not able to see the traceback in nowhere.

class BidConsumer(JsonWebsocketConsumer):

    def receive_json(self, content):
        print(content['non_existing_key'])  # KeyError is expected

I just noticed the error because I lost the connection to websocket on browser but I can’t see anything on console.

I’m using Python 3.6.4, Django 2.0.2, Channels 2.0.0 and since I’m still testing I didn’t configure anything as ASGI backend.

This only happens when Channels are running via runserver if I use via daphne I’m able to see exceptions as expected.

Alright! I’ve released that fix in daphne 2.0.1.

It’s works! Using the code from master solved the issue.

Thank you
