@ManikandanUV What version of `SQLAlchemy` and `Flask-AppBuilder` do you have installed in each server?

Can anyone give us reproduction steps? Cos trying this with a "minimal" 2.3.4 and the upgrading to 2.4.0 neither myself nor @ephraimbuddy have been able to reproduce this, so we're...

Thanks @joshowen that's very helpful

Okay, I've found the source of the confusion, and the path needed to trigger this behaviour. Run airflow webserver with < 1.10.13 in RBAC mode, where FAB creates it's tables....

Someone will need to check how this interacts with task mapping first please

@uranusjr Can you take a look at this ASAP please so we can get a fix for this out in 2.4.1?

@kxepal What is the timetable/schedule parameter for the DAG(s) with this problem?

_Everything_ is converted to a timetable now under the hood (and had been since timetables were introduced) so it's not as simple as an `if`.

@kxepal Creating a minimal stand-alone reproduction case if you can ("here's a dag, run it/backfill it for X" sort of thing)
