I have been trying to find help for this problem and there hasn't been too much success. I keep getting this error. I was following this guide: https://cloud.google.com/community/tutorials/cloud-iot-gateways-rpi and I haven't been able to get past step 14.

I was able to successfully get the gateway running but had to manually modify the script. Make sure that you have updated the run-gateway shell script to point to your registry ID and project ID.
If any of the parameters are incorrect (e.g. device, project, region) then your device will be disconnected from the device bridge.
