'Airflow 2.1.0 - DAG 'XXXXXXXX' not found in serialized_dag table
We recently upgraded from Airflow 1.10.12 to Airflow 2.1.0 and are getting issues errors like this in the UI for each of our dags.
We have upgraded the version from 1.10.12 to 1.10.15 and it was successful. Then from 1.10.15 we have upgraded to 2.1.0 and facing this issue.
File "/home/airflow/.local/lib/python3.6/site-packages/airflow/models/dagbag.py", line 249, in _add_dag_from_db
raise SerializedDagNotFound(f"DAG '{dag_id}' not found in serialized_dag table")
