this is my asgi.py file:

import os
import django
from channels.routing import get_default_application
from channels.layers import get_channel_layer

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'ProfilesApp.settings.development')
django.setup()
application = get_default_application()
channel_layer = get_channel_layer()

settings.py

ASGI_APPLICATION = "ProfilesApp.routing.application"
WSGI_APPLICATION = 'ProfilesApp.wsgi.application'
CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [os.environ.get('REDIS_URL', 'redis://localhost:6379')],
        },
    },
}

Please let me know how to fix that, thanks in advance

    asgi.py should be like this :

    import os
import django
from channels.routing import get_default_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")
django.setup()
application = get_default_application()

    and ProcFile should be like this

    web: daphne myproject.asgi:application --port $PORT --bind 0.0.0.0 -v2
chatworker: python manage.py runworker --settings=myproject.settings.production -v2

    You are using wrong asgi configuration which was intended for channels 1.x

    as documentation states should look like

    """
ASGI entrypoint. Configures Django and then runs the application
defined in the ASGI_APPLICATION setting.
"""

import os
import django
from channels.routing import get_default_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproject.settings")
django.setup()
application = get_default_application()
