[GitHub] [airflow] ldacey commented on issue #25200: DAG Run fails when chaining multiple empty mapped tasks

   FYI - ran into the same issue on Airflow 2.3.4. I had to revert back to 2.3.2 for a stable experience for now, and I had to delete one row from my task instance table (a UPDATE was trying to change map_index to 0 which already existed, apparently, so the primary constraint was violated and the scheduler crashed).
   
   In my case, none of my dynamic tasks happen to have empty lists though - there are values.
