AsyncJsonWebsocketConsumer and channel redis doesn't work

Django==2.2.6
django-heroku==0.3.1
daphne==2.4.0
gunicorn==19.9.0
requests==2.22.0
channels==2.3.1
channels-redis==2.4.1

I have a simple consumer program that I am testing my redis server, but I don’t see the channel function executing.

from channels.generic.websocket import AsyncJsonWebsocketConsumer

class backEndConsumer(AsyncJsonWebsocketConsumer):

    async def websocket_connect(self, type):
        self.channel_name = "first"
        await self.channel_layer.group_add("link", self.channel_name)
        await self.accept()

    async def websocket_disconnect(self, close_code):
        await self.close()
        await self.channel_layer.group_discard("link", self.channel_name)
        # Called when the socket closes
        
    async def websocket_receive(self, text_data=None, bytes_data=None):
        await self.send("Connected")
        await self.channel_layer.group_send(
        "link",
            {
               "type": "link.send",
               "message": "msg from websocket",
            })       
        
#channel layer functions 
    async def link_send(self, event):
        print("got message: " + event["message"])
        await self.send("triggered!")

my settings.py has this

redis_host = os.environ.get('REDIS_HOST', 'localhost')
CHANNEL_LAYERS = {
    "default": {
        "BACKEND": "channels_redis.core.RedisChannelLayer",
        "CONFIG": {
            "hosts": [(redis_host, 6379)],
        },
    },
}

I believe I followed most of the examples (including the multichat example). But my code doesn’t seem to work. I have found people with issues similar to mine and it seems like they found work arounds, but it didn’t apply to my code.

I’ve moved my question to https://stackoverflow.com/questions/59886447/interactions-between-http-and-websocket-connections-in-django-channels

@hishnash I am trying to figure out a way to build an IOT device, with a http requests coming from DialogFlow and then using websocket to talk to my embedded device.

I still have questions about the inner workings of django-channels, I will probably reform my questions and put them on stackoverflow.

edit: I tried to put the 200 request in webhook_reg(), which gets called from websocket_reg(), it gets the same no handler for message type.
