I have created new dags today and this is what I see in the logs near time
of creation
```
sqlalchemy.exc.InvalidRequestError: This Session's transaction has been
rolled back due to a previous exception during flush. To begin a new
transaction with this Session, first issue Session.rollback(). Original
exception was: (MySQLdb._exceptions.IntegrityError) (1062, "Duplicate entry
'my_dag2' for key 'serialized_dag.PRIMARY'")
[parameters: ('my_dag2', '/home/ec2-user/airflow/dags/spiremak_test.py',
70986863378950560, '{"__version": 1, "dag": {"edge_info": {}, "timezone":
"UTC", "_task_group": {"_group_id": null, "prefix_group_id": true, "tooltip":

"airflow.operators.bash", "_is_dummy": false, "bash_command": "echo

datetime.datetime(2022, 2, 4, 9, 42, 40, 154149),
'13e704f28bd83ca69cd2969c9aa6c173')]
```
and
```

datetime.datetime(2022, 2, 4, 9, 45))]
```
However I don't see anything in the logs after every 5 mins which is when I
expect the dag to run
