On a Docker Chirpstack ver. 4.3 , the example "nqueue_downlink.py" (https://www.chirpstack.io/docs/chirpstack/api/python-examples.html#enqueue_downlinkpy) works fine.
When we try to execute the following python code for multicast downlink :
server = "localhost:8080" dev_eui = "0080e1150546f8eb" api_token = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJhdWQiOiJjaGlycHN0YWNrIiwiaXNzIjoiY2hpcnBzdGFjayIsInN1YiI6ImMyOGM5M2I4LTdlNWMtNGYzOS1hZTA2LWFlNDU3ZjYxNzcwNiIsInR5cCI6ImtleSJ9.7cbczN8WJ5ZNGoQwjZwFLaHiBThGDMJ-1T_uaUTT2F4" data = [ 0x84, 0x9b, 0x00, 0x08, 0x00, 0x02, 0x01 ] mcast_group_id = "4b2b9d7c-776f-4e54-b81d-d17178d6d558" channel = grpc.insecure_channel(server) client = api.DeviceServiceStub(channel) auth_token = [("authorization", "Bearer %s" % api_token)] req = api.EnqueueMulticastGroupQueueItemRequest() req.queue_item.data = bytes(data) req.queue_item.f_port = 2 req.queue_item.multicast_group_id = mcast_group_id resp = client.Enqueue(req, metadata=auth_token)
We are getting the folowing error message :

When we try the "EnqueueMulticastGroupQueueItemRequest()" with Node_Red it works fine.
Does anybody knows about this error message ?
