With a restricted libarian account (only some acq permissions) it is not possible to see or edit vendors in acquisition . The error message "Something went wrong: Error: Authorization failure. Missing required permission(s)." appears. The patron would need the acquisition permissions which includes budget permissions among other things, otherwise the API blocks the request. To recreate: 1. Log in as superlibrarian 2. Search for a user, for example borrowernumber=17 7. Give permissions for catalogue (staff access) and manage_vendors 8. Log in with this account 9. Go to Acquisition module 10. Click on Search Vendors Check that the error message mentioned above appears
