2025-05-15 09:01:28 UTC 🚨 Branch Integration: The build pipeline contains failing jobs for this merge request

We couldn't automatically merge the commit 16e35ec259 into staging-20.
Build pipeline has failing jobs for 4d429f1:

• typecheck

⚠️ Do NOT retry failed jobs directly (why?).

What to do next?

• Investigate the failures and when ready, re-add your pull request to the queue!
• If your PR checks are green, try to rebase/merge. It might be because the CI run is a bit old.
• Any question, go check the FAQ.

If you think the errors come from a logical conflict with the target branch, you can create a fix by commenting this pull request with /create-fix-branch -b staging-20

Details

Since those jobs are not marked as being allowed to fail, the pipeline will most likely fail.
Therefore, and to allow other builds to be processed, this merge request has been rejected and the pipeline got canceled.
