The backport to 4.3-1.2-wzd failed:

The process '/usr/bin/git' failed with exit code 1

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-4.3-1.2-wzd 4.3-1.2-wzd
# Navigate to the new working tree
cd .worktrees/backport-4.3-1.2-wzd
# Create a new branch
git switch --create backport-4239-to-4.3-1.2-wzd
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 83e987567101be410a7e0d1ab83e4985499dda37
# Push it to GitHub
git push --set-upstream origin backport-4239-to-4.3-1.2-wzd
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-4.3-1.2-wzd

Then, create a pull request where the base branch is 4.3-1.2-wzd and the compare/head branch is backport-4239-to-4.3-1.2-wzd.
