Goals

I am trying to migrate objects from my Draft table to BDraft and CDraft tables, depending on the type of object.

Expected Results

I have already made a similar migration which worked well. So I expect found my objects in the expected tables after migration

Actual Results

The app crashes when trying to create the object with primary key during migration

Steps to Reproduce
