The backport to 2.3 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-2.3 2.3
# Navigate to the new working tree
cd .worktrees/backport-2.3
# Create a new branch
git switch --create backport/backport-518-to-2.3
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 781744c6b142193528b101eb05a758932cba00de
# Push it to GitHub
git push --set-upstream origin backport/backport-518-to-2.3
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.3

Then, create a pull request where the base branch is 2.3 and the compare/head branch is backport/backport-518-to-2.3.
