Getting error message running Django server

I’m not able to run python manage.py runserver. I was able to run python manage.py migrate successfully. I even changed ASGI_APPLICATION = "MyProject.asgi.application" to ASGI_APPLICATION = "routing.application" which didn’t work. Here is the error I get

1 There's an ImportError halfway through the stack trace that you should address. Make sure StopConsumer is available to import from channels.exceptions – schwartz721 Commented Mar 28 at 22:52
You are having an improperly configured error in your traceback error stack. Can you help us with your asgi, static/media files? Have you ensured that your project points to the ASGI_APPLICATION instance in your settings? – Blaisemart Commented Mar 29 at 7:21
