The backport to 2.13 failed:

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

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-2.13 2.13
# Navigate to the new working tree
pushd ../.worktrees/backport-2.13
# Create a new branch
git switch --create backport/backport-12789-to-2.13
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 3cc154aac8ef46f6a209a769086c80c3a4253b2b
# Push it to GitHub
git push --set-upstream origin backport/backport-12789-to-2.13
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-2.13

Then, create a pull request where the base branch is 2.13 and the compare/head branch is backport/backport-12789-to-2.13.
