Expected:
first_task TI does not change (stays as none)
create_and_transfer_roster TI is run
Actual:
first_task TI gets its state set to removed
create_and_transfer_roster TI is not run, backfill errors with
airflow.exceptions.AirflowException: Task first_task not found
[~bolke] if you think these are related to your changes (addition of
task.REMOVED state/backfill changes) do you mind taking a look? Otherwise let
me know and I can do so.
> Backfills delete existing task instances and mark them as removed
