We run Moodle 3.4 and have noticed that an assignment with no submission types (e.g. files, Mahara or text input) causes non-editing tutors to receive a blank page, except for the normal navigation and top bar/menus. I.e. the assignment plugin has returned nothing.
If we add "&action=grading" to the end of the assignment URL the user receives a Moodle error "error/nopermission".
The user in question can "view/grade submissions" for other assignments on the same course that DO have submission types.
This leads us to believe there is potentially a bug as non-editing tutors should still be able to grade assignments.
Has anyone experienced this/confirm if this is by design or if we have stumbled across a role default permissions bug?
The assignment has no permission overrides.
