The backport to 8.15 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-8.15 8.15
# Navigate to the new working tree
cd .worktrees/backport-8.15
# Create a new branch
git switch --create backport-2346-to-8.15
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 9c959971a561f1cf1a12d18d3ad652afc4f97f1d
# Push it to GitHub
git push --set-upstream origin backport-2346-to-8.15
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-8.15

Then, create a pull request where the base branch is 8.15 and the compare/head branch is backport-2346-to-8.15.
