RuntimeError: no running event loop

When I run systemctl start daphne I get the following error

Traceback (most recent call last):

from channels.http import AsgiHandler
from channels.routing import ProtocolTypeRouter, URLRouter, ChannelNameRouter

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "portal.settings")
django.setup()

from api.routing import websocket_urlpatterns
from channels.auth import AuthMiddlewareStack
from api.consumers import MultiplexConsumer


application = ProtocolTypeRouter({
  "http": AsgiHandler(),
  "websocket": AuthMiddlewareStack(
        URLRouter(
            websocket_urlpatterns
        )
    ),
})

Duplicate of django/asgiref#292 — caused by the presence on the ASGI_THREADS environment variable. Should be fixed in the next ASGIRef release.

thanks for the quick reply, any idea how long before the next release?
