The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 128

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/alerting/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/alerting/backport-2.x
# Create a new branch
git switch --create backport-1245-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 c2f45de27ae7b9ae2f87300728d9f940c7b014a6
# Push it to GitHub
git push --set-upstream origin backport-1245-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/alerting/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport-1245-to-2.x.

@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.
