[GitHub] [airflow] uranusjr commented on pull request #17544: Rescue if a DagRun's DAG was removed from db

uranusjr commented on pull request #17544:
URL: https://github.com/apache/airflow/pull/17544#issuecomment-898243405


   For future reference, the complete steps to reproduce this from the web UI is:
   
   1. Create a DAG with a subDAG that runs for a long-ish time. Wait for them to show up in the web UI.
   2. Run the DAG (thus trigging the subDAG).
   3. delete the parent DAG from the web UI. (This does not delete the subDAG.)
   4. Try to block the subDAG’s unfinished run from step 2. (Should fail with `SerializedDagNotFound` before this patch.)
