The backport to main 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-main main
# Navigate to the new working tree
pushd ../.worktrees/backport-main
# Create a new branch
git switch --create backport/backport-16105-to-main
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 af105b1bb547fc8843fab0986f1aa60454529d54
# Push it to GitHub
git push --set-upstream origin backport/backport-16105-to-main
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-main

Then, create a pull request where the base branch is main and the compare/head branch is backport/backport-16105-to-main.
