Error message

processing engine trigger {trigger_id} not found in database {db_id}

What it means

ProcessingEngineError::TriggerNotFound, raised when the processing engine manager looks up a trigger by TriggerId in a database and finds none registered; typical when invoking, disabling, or deleting a trigger that was never created or was already removed.

Solutions

1. Verify the trigger id and database id with a list/show-triggers call
2. Create the trigger before referencing it
3. Handle the already-deleted case as a no-op for idempotent deletes

When it happens
