The backport to 5.0.x 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-5.0.x 5.0.x
# Navigate to the new working tree
cd .worktrees/backport-5.0.x
# Create a new branch
git switch --create backport-14505-to-5.0.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 cf5922a404cd61a65b59fc97e622b45681e6529e
# Push it to GitHub
git push --set-upstream origin backport-14505-to-5.0.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-5.0.x

Then, create a pull request where the base branch is 5.0.x and the compare/head branch is backport-14505-to-5.0.x.
