Just as a heads up that forum behavior has changed since the last release, and that new courses are supposed to default to a mode where you can mark units as discussable via a checkbox in its access controls:

https://openedx.atlassian.net/wiki/spaces/COMM/pages/3470655498/Discussions+upgrade+Sidebar+and+new+topic+structure#How-do-I-enable-discussions-sidebar?

I say "supposed to" because it's not currently working for me on tutor nightly. FYI @ayub02

[ayub02]

I was under the assumption that the new discussion provider (sidebar) is behind a waffle flag discussions.enable_new_structure_discussions. @ghassanmas can you please confirm if this flag has been enabled for the courses or the environment that you are working with?

There is only one reason for this issue to be an invalid URL.

• A Valid URL: ${BASE_URL}${getConfig().PUBLIC_PATH}:courseId/posts OR https://discussions.stage.edx.org/course-v1:arbisoft_acca+cs1023+2021_T4/posts
• A Invalid URL: ${BASE_URL}null/:courseId/posts OR course-v1:arbisoft_acca+cs1023+2021_T4/home OR https://discussions.stage.edx.orgundefined/course-v1:arbisoft_acca+cs1023+2021_T4/posts

Valid Example
Four parts are required to build a valid URL.

1. BASE_URL: https://discussions.stage.edx.org
2. PUBLIC_PATH: / OR /any-slug/
3. courseId: course-v1:arbisoft_acca+cs1023+2021_T4
4. tab: posts

https://discussions.stage.edx.org/course-v1:arbisoft_acca+cs1023+2021_T4/posts

Note:
The above issue can be raised because of an invalid URL or undefined PUBLIC_PATH. It is common practice in openEdx community to define custom PUBLIC_PATH for MFEs. We are following the same pattern to make it easy for openEdx community. PUBLIC_PATH configure in frontend-platform and its default value is /.

[awais-ansari]

I was debugging this issue in the tutor Quince Branch Demo. The issue is with PUBLIC_PATH. The below images are from Quince Demo. It is creating invalid URLs because of an invalid PUBLIC_PATH.

• Tutor PUBLIC_PATH: /discussions
• Tutor BASE_PATH: /discussions:courseId

It Should be

• PUBLIC_PATH: /discussions/
• BASE_PATH: /discussions/:courseId

[xitij2000]

I think openedx/frontend-app-discussions#613 should fix the issue.

[mariajgrimaldi]

@xitij2000: thanks! Please let us know when the PR gets merged so we can open a backport for Quince.

[mariajgrimaldi]

I added the release blocker label, although the discussions MFE can be disabled, so the platform could still work without it. I'll leave it as is to focus our attention on it.

[awais-ansari]

@mariajgrimaldi This issue has been resolved and merged in master and Quince too.

[mariajgrimaldi]

I'll be closing this then. Thanks @awais-ansari!
