Hi @kwacky1, PR mentions it would fix https://github.com/OpenSourceFellows/dashboard_server/issues/88
and is marked a bug fix as well.
Based on what I know integration with notion isn't complete yet so please share which tests this PR is about. Apologies the review took a bit of time but thanks for your contribution and look forward to making progress.

Hey there @SAUMILDHANKAR I don't have access to the issue any more and don't really remember what the issue was but based on the changes it just fixes a few little things that should get the tests working, but if notion is not required then feel free to close this PR.

@kwacky1 thanks a lot for getting back. Apologies I moved the issue to a private repo since we now have two repos (front and back end). Notion is required so not planning to close this PR. If you want to continue working on this I can bring the issue details in a comment here. Otherwise I will just wait till notion is integrated and then review this PR again to check if tests working fine.

If you want to work on any other issue is this project please let me know as well. Thank you and have a great year 2026 :)
