The backport to ros2-ign 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-ros2-ign ros2-ign
# Navigate to the new working tree
cd .worktrees/backport-ros2-ign
# Create a new branch
git switch --create backport-71-to-ros2-ign
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 648c15296b50f5864ab7a8a200b77dcee0f837bd
# Push it to GitHub
git push --set-upstream origin backport-71-to-ros2-ign
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-ros2-ign

Then, create a pull request where the base branch is ros2-ign and the compare/head branch is backport-71-to-ros2-ign.
