Primero upserts not working; case_id undefined

[aleksa-krolls]

I'm worried we broke something in our recent round of changes that causing all sorts of testing questions... it looks like case_id is returning undefined when we would expect to see a value.

See L463 in this run and below. Logs show "case_id": "or_op||undefined" when there is indeed "case_id": "a1f4a4f9-ee68-4a94-89b2-96ddc868bc97".
