Deadletter table empty exception_msg


What does it mean when a process instance has a record in deadletter table but the exception_msg is empty?

They seem to be mostly if not all “timer” related. Under what conditions would a timer job go to deadletter?

maybe it’s not a Flowable Exception

If a timer job is in dead letter, it means certainly that the next task (after the timer) is synchronous and fails.
