Student access error in imported courses

[sbernesto]

Hi, @regis

Tutor version: 13.1.1

Fresh install, without plugins

When I import a course already made, with the advanced options of only by invitation and hidden in the catalog, it shows the error “There was an error loading this course.” to students who are added through the instructor/membership menu.

If I remove the option of only by invitation and that it be shown in the catalog, so that the students self-enroll in the course they can enter to course without problems.

This is the log of the imported course and I don’t see any problem in its import

course import - Pastebin.com

I have tried it on the demo platform of demo.openedx.overhang.io and got the same error

In the logs I don’t find anything abnormal, more than a caddy

I still add all the log generated by the user when trying to enter the course.

After several tests I have found that it is the MFE that gives me an error, since I have deactivated it with these options in this post, users can enter the course without problems.

Course Page Not Found In Maple Release

This was my mistake. The solution is (followed by document https://openedx.atlassian.net/wiki/spaces/COMM/pages/2603816700/Maple) In LMS admin dashboard. Navigate to lms_domain/admin/waffle/flag/ Add flag courseware.use_legacy_frontend Add flag course_home.course_home_use_legacy_frontend Restart lms and cms Try to access course page [Screen Shot 2021-12-21 at 13.51.18]

But as it says right there in that post, it is not recommended to disable it since it has not been tested.

On the other hand, install tutor in its lilac 12.2.0 version and it works perfectly.

I have tried to see the mfe logs but I can’t find it, since unfortunately both the lms and caddy logs don’t say where the mfe fails when rendering the course

[regis]

I have no idea how to troubleshoot this, but just to give you a pointer: MFE don’t have logs, because they don’t have server-side code. The whole point of microfrontends is that all the code is javascript that runs in the browser. Thus, to troubleshoot this issue you should have a look at the developer console in your browser.

[sbernesto]

Thanks @regis for reminding me of the browser console.

I didn’t know that’s why there are no logs, but you just gave me an idea and it seems to work.

Check the console and indeed the MFE sends to call an api and it returns the following result

Checking in detail the url of the error the api sends this message

{"detail":"Not found."}

Then go back to studio.

I changed the Course Visibility In Catalog option from none to about and it seems to let me into the course with no problem.

and the api already returns information

{"can_show_upgrade_sock":false,"verified_mode":null,"can_load_courseware":true,"celebrations":{"first_section":false,"streak_length_to_celebrate":null,"streak_discount_enabled":false},"course_access":{"has_access ":true,"error_code":null,"developer_message":null,"user_message":null,"additional_context_user_message":null,"user_fragment":null},"course_id":"course-v1:BUnited+BU-0001+ 2022_S1","is_enrolled":true,"is_self_paced":false,"is_staff":false,"number":"BU-0001","org":"BUnited","original_user_is_staff":false,"start":" 2020-06-06T00:00:00Z","tabs":[{"tab_id":"courseware","title":"Course","url":"http://apps.dev.lan/learning/ course/course-v1:BUnited+BU-0001+2022_S1/home"},{"tab_id":"progress","title":"Progress","url":"http://apps.dev.lan/ learning/course/course-v1:BUnited+BU-0001+2022_S1/progress"},{"tab_id":"dates","title":"Dates","url":"http://apps.dev. lan/learning/course/course-v1:BUnited+BU-0001+2022_S1/dates"},{"tab_id":"discussion","title":"Discussion","url":"http://dev. lan/courses/c ourse-v1:BUnited+BU-0001+2022_S1/discussion/forum/"}],"title":"Basic Word","username":"net","user_timezone":null}

In summary or solution for the moment is: Avoid setting courses to none in the Course Visibility In Catalog variable and using about, for invite-only courses

[regis]

Do you think that this is a bug? Should you report it to the BTR? Issues · openedx/build-test-release-wg · GitHub

[sbernesto]

Thanks, I have opened a post in the open edx forum, since github won’t let me.

[ghassanmas]

@sbernesto were you able to find a solution?, I am facing the same exact problem

[sbernesto]

hi,

I managed to solve the error by changing the visibility variable in the catalog from none to about

[ghassanmas]

Yeah we went around it by setting it to “both”, setting it to “about”, would it still be visible in dashboard?, or just if someone has the same link I guess

[sbernesto]

It just doesn’t list it on the dashboard, but it can be found with discovery and let into the about page.
