The backport to release-1.15 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-release-1.15 release-1.15
# Navigate to the new working tree
cd .worktrees/backport-release-1.15
# Create a new branch
git switch --create backport-3449-to-release-1.15
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick --mainline 1 1fa2666e3f324760c2cc57ae0b19be369295b26e
# Push it to GitHub
git push --set-upstream origin backport-3449-to-release-1.15
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release-1.15

Then, create a pull request where the base branch is release-1.15 and the compare/head branch is backport-3449-to-release-1.15.
