django deployment : ASGI app does not loading static files

Question

WhiteNoise introduces itself : whitenoise works with any-WSGI compatible app.
Then, what package should I use for ASGI app??

Let's suppose url /chatting/ is rendered by index.html.

For the first time we access /chatting/. When I click html li tag, this code is executed.

// Room join/leave
$("li.room-link").click(function () {
    roomId = $(this).attr("data-room-id");
    if (inRoom(roomId)) {
        // Leave room
        $(this).removeClass("joined");
        webSocketBridge.send({
            "command": "leave",
            "room": roomId
        });
    } else {
        // Join room
        $(this).addClass("joined");
        webSocketBridge.send({
            "command": "join",
            "room": roomId
        });
    }
});

joined class added successfully!!

However, after that(click event) Nothing is happen.
when I see log, it seems that websocket connection is still working.

Currently In my project, ASGI app failed to load jQuery static file.
What should I do for ASGI app to load jquery static file.

I deployed my django project on Heroku. So I'd like to fix it in production environment.(in development environment it is working fine.)

below is my heroku Procfile setting.

web: gunicorn multichat.wsgi --log-file -
web2: daphne multichat.asgi:channel_layer --port $PORT --bind 0.0.0.0 -v2
worker: python manage.py runworker -v2

and it is index.html full code.

WhiteNoise will work with Channels, just add it to the MIDDLEWARE list in settings.py: http://whitenoise.evans.io/en/stable/django.html#enable-whitenoise
