Order app permissions error

Overview: When I open the orders app, I get a permission error and cannot display PO or PO Line details.

Steps to Reproduce:

1. Log into FOLIO-testing as diku_admin
2. Go to Orders app
3. Try to open a PO from the results list

Expected Results: Third pane should open with the PO details, and then the user should be able to open PO Line details

Actual Results: Thurs pane doesn't open, plus there's a permissions error message at bottom right when I open the orders app.

Additional Information: I also tried updating diku_admin's permissions, but that didn't seem to help. See attached video.
