I made a django project using channels.
And I want to deploy it. Because my project uses channels, I should set up ASGI based environment.
I pushed my project and succeeded. So I got URL address.
https://demo-multichat.herokuapp.com
As you can see, Application error occured.
I got log.

I thought something goes wrong as to Procfile. Below is my Procfile setting.
web: daphne multichat.asgi:channel_layer
worker: python manage.py runworker
In my local terminal, I executed each line.
1st $ python manage.py runworker
2017-09-07 15:12:43,889 - INFO - runworker - Using single-threaded worker.
2017-09-07 15:12:43,889 - INFO - runworker - Running worker against channel layer default (asgi_redis.core.RedisChannelLayer)
2017-09-07 15:12:43,889 - INFO - worker - Listening on channels chat.receive, http.request, websocket.connect, websocket.disconnect, websocket.receive
It is fine. Good.
2nd $ daphne multichat.asgi:channel_layer

I got error messages.
How can I fix this issue?? I need your help.
If you need my project source code, I leave github repository url as comment.
