The backport to 1.3 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-1.3 1.3
# Navigate to the new working tree
pushd ../.worktrees/backport-1.3
# Create a new branch
git switch --create backport/backport-6307-to-1.3
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 72c0ed10af9b00be806b47484dc0a49cea38de6b
# Push it to GitHub
git push --set-upstream origin backport/backport-6307-to-1.3
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-1.3

Then, create a pull request where the base branch is 1.3 and the compare/head branch is backport/backport-6307-to-1.3.
