Reproduce the failure in the web UI, then inspect lib/Service/NotesService.php around line 128 and lib/Controller/NotesController.php around lines 160-161, where the stack trace reaches file creation. Compare behavior for a newly created user with an existing user and trace the NotPermittedException. Done means a new user can create a note successfully without the exception.
