Somehow i got it working, added: db.session.rollback(), before append

Dont know whether its the right approach

it's not. you need to identify where that Package object is getting generated.

If it were me, I'd be using pdb, however, if you want a more high level approach, you can use the transient_to_pending event to intercept where a Package object is unexpectedly getting attached:
