This error concerns the Dismiss button:

This error occurs here:

elif request.method == 'DELETE':
    raise NotImplementedError()

This banner was added in this MR. But the backend part was not prepared for this at all.

Hello, @muhammadadeeltajamul, You have been working on this task. Can you tell me if there are plans to continue this work? Would it be possible to add a variable to control the display of the banner? It could help manage user preferences or control this content.
As I understand it, in the current implementation the Dismiss button is not needed at all.

Start at cms/djangoapps/contentstore/views/course.py around line 301 and trace the DELETE request triggered by the Studio Discussions x-blocks banner. Review pull request 31645 and the existing issue discussion to determine whether Dismiss should be removed or supported. Done means the banner action no longer produces a 500 response and its intended behavior is covered by the relevant project tests.
