The backport to release/v1.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-release/v1.x release/v1.x
# Navigate to the new working tree
cd .worktrees/backport-release/v1.x
# Create a new branch
git switch --create backport-440-to-release/v1.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 e6cff29f26b6ed19b4981a5326160cb8ed8508ef
# Push it to GitHub
git push --set-upstream origin backport-440-to-release/v1.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release/v1.x

Then, create a pull request where the base branch is release/v1.x and the compare/head branch is backport-440-to-release/v1.x.
