Daphne server on Heroku will not allow app to start

The dockerized app successfully uploads and the code is hosted on Heroku's docker container registry. I can shell inside, run `python manage.py migrate` or `./manage.py runserver`, etc.  

So the chokepoint likely seems to be the daphne command I'm running.  

`web: daphne config.asgi:application --port $PORT --bind 0.0.0.0 -v2`  

That^ is what I'm running, and here's the output:  

web.1]: Starting process with command `/bin/sh -c daphne\ -b\ 0.0.0.0:\29689\ config.asgi:application\ -v2`

It just spits out all the ENV vars. The Heroku app will not open.  

If I run it locally using a Procfile and then go to localhost, I will see Daphne's 500 Internal Server Error page.  

Any idea?  

I came across this https://github.com/django/channels/issues/872 issue in which Andrew briefly mentions that a Raven install may cause issues.  
Though my app is using Raven, I've commented out all of its related settings for now.  

He also mentions that it isn't an issue related to not running `runworker`.
