The backport to release-1.8 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-release-1.8 release-1.8
# Navigate to the new working tree
cd .worktrees/backport-release-1.8
# Create a new branch
git switch --create backport-2313-to-release-1.8
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick --mainline 1 1c1f362e28a0b5c5616392f99cb27fa44986cec6
# Push it to GitHub
git push --set-upstream origin backport-2313-to-release-1.8
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release-1.8

Then, create a pull request where the base branch is release-1.8 and the compare/head branch is backport-2313-to-release-1.8.
