We've gotten reports that Anonymous courseware access is broken in Nutmeg, likely due to this PR.

This ticket would include:

  1. Fix the anonymous user handling, for the courseware API view.
  2. Add new tests to make sure that this doesn't break again for anonymous users.
  3. Backport this fix to Nutmeg.

Hello,

I am joining this conversation with and behalf of my colleague Gabi who contacted you on e-mail.

When trying to access a course anonymously, we're experiencing this issue with Nutmeg installed using tutor v 14.0.4:

The page will display: There was an error loading this course.

We had tried to add the suggested following waffle flags in django for the following course: course-v1:OsloMetX+SP22+01

Waffle flags added:
grades.assume_zero_grade_if_absent
seo.enable_anonymous_courseware_access

Here's a stacktrace from ~/.local/share/tutor/data/lms/logs/all.log when trying to access the course anonumously:

Hi, I was having a look into this issue and it seems like the above exception is actually fixed with the removal of the ASSUME_ZERO_IF_ABSENT waffle flag under openedx/edx-platform#30978. Now it assumes zero grade by default. As a result of this PR, the issue mentioned above is resolved for anonymous users.

Currently, the course home is still not loading when the MILESTONES_APP feature is set to True.

  • Course home is getting There was an error loading this course. for anonymous users as the backend raises an unhandled exception that results in 500.
  • MILESTONES_APP is required to enable the entrance exams for a course.
  • Exception is raised intentionally for anonymous users when the milestones app is enabled.
  • Exception message says Anonymous access is not allowed for course runs with milestones set..
  • Here is the link to the responsible code snippet.
  • This exception seems to be intentional when Milestones are enabled for a course.
  • Exception Traceback is added at the end of this message.

Possible Solutions:

  1. Log the exception and show a meaningful error message to the user.

TRACEBACK:

Just a FYI that I'm hoping to see this in the post-Olive release, as I used to have some public access courses, and I had to take them down when I upgraded to Nutmeg due to this bug.
