Did you reboot or shut down in there anywhere? There was issues in the past with states getting out of sync and a reboot would clear whatever cache ZWJS has going on and then it would sync back up correctly. I think it was fixed for 2.4.0 but maybe something similar is back.
Debug logs in a separate report for this would be very helpful, so staff can see what message is coming into the driver to cause the error. I assume you mean there is a red error in the logs?
