The backport to 1.5 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-1.5 1.5
# Navigate to the new working tree
cd .worktrees/backport-1.5
# Create a new branch
git switch --create backport-8034-to-1.5
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 2f6b31f0a0d34253f981ad922f4f99ae23dd6d69
# Push it to GitHub
git push --set-upstream origin backport-8034-to-1.5
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-1.5

Then, create a pull request where the base branch is 1.5 and the compare/head branch is backport-8034-to-1.5.
