Hi, this indeed indicates that a REST handler is requesting the ExecutionGraph from a JobManager which does not run in the same ActorSystem. Could you please tell us the exact HA setup. Are your running Flink on Yarn with HA or do you use standalone HA with standby JobManagers?
It would be really helpful if you could also share the logs with us.
