Getting error "invalid warehouse_id" when trying to update any transaction in Zoho books

Getting error "invalid warehouse_id" when trying to update any transaction in Zoho books

I got a message from Zoho saying that the Warehouse and Branch has been merged into one category "Locations"
Once I migrated to this setup I was no longer able to edit any invoice / create creadit notes - got an error saying "invalid warehouse_id"
I never had to use "warehouse_id" in the past in Zoho books.
Not sure how to resolve this.
