Left this comment in the PR as well, but I'll add it here too for visibility. Once successfully backported, we can close this issue.

@kennyzhang0819 Looks like the auto backport for this PR failed. Could you please manually create a backport PR? To do that, you'd want to:

1. Create a dev branch from the 2.x branch.
2. Copy the changes from this PR to that branch (I usually use git cherry-pick to do this).
3. Create a new PR from your 2.x dev branch to the 2.x branch in alerting repo.

Just did that. See #1272
