Problem in running ASGI environments while deploying app Django Rest

Question

I am developing an app using Django,I have deployed it on Google Cloud Platform initially using WSGI environment,now I have made addition in app and used channels due to which I have to shift from WSGI to ASGI, but I am getting errors while deploying to Google Cloud Platform when I use ASGI environment

I got the error: respiter = self.wsgi(environ, resp.start_response) TypeError: __call__() takes 2 positional arguments but 3 were given

I commented the all content of WSGI file when I want to use ASGI environmnet,here's me related code:

ASGI FILE:

import os
import django
from channels.routing import get_default_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'Frames.settings')
django.setup()
application = get_default_application()

WSGI FILE (which I have commented):

"""
WSGI config for Frames project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/2.2/howto/deployment/wsgi/


import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'Frames.settings')

application = get_wsgi_application()"""

main.py:

from Frames.asgi import application
app = application

Settings.py(Main changes and I have removed all WSGI related from settings.py)


ASGI_APPLICATION = "Frames.routing.application"

CHANNEL_LAYERS={
    "default":{
      "BACKEND": "channels_redis.core.RedisChannelLayer",
      "CONFIG": {
                "hosts": [("localhost", 6379)],
            },
    },
}

How can I run ASGI environment? If I missed something in showing my code I can also show that,I can't get what the problem is,Is my way of deploying ASGI app is correct?

It automatically load from main.py file which I have mentioned,where it call ASGI file (which is the entry point) — Nabeel Ayub, Dec 30 '19 at 09:25
After you commented everything from WSGI you still got the respiter error? Or what is the error that you get after commenting all the WSGI? — Stefan Neacsu, Dec 30 '19 at 10:18

App Engine Standard currently does not support ASGI.

To work with ASGI you should use App Engine Flexible, where you can tweak the environment much further.

Then, you might find useful the guide in the GAE flex documentation about Creating Persistent Connections with WebSockets.
