GCP Integration on Chirpstack

Hello! I have been trying to get messages from some sensors being sent to a RAK gateway and concentrator from Chirpstack through to my GCP Pub/Sub. However, it seems that the LoRa server isn’t sending any messages to my GCP topic.

The gateway definitely receives frames from the sensors, but I am having a hard time getting that payload onto my GCP function. Any suggestions would be great! Thanks a lot in advance!

Have you confirmed the issue is only with the GCP Pub/Sub integration? Between the gateway receiving the uplink and ChirpStack forwarding this event to GCP Pub/Sub are a couple of steps which could fail (e.g. wrong frame-counter, mic error, etc…).

One way to confirm if ChirpStack successfully processed the uplink is by checking the device events in the web-interface.
