[github-actions]

The backport to release-1.5.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-1.5.x release-1.5.x
# Navigate to the new working tree
cd .worktrees/backport-release-1.5.x
# Create a new branch
git switch --create backport-2535-to-release-1.5.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick ---mainline 1 f168d646a79949de404a20d334472d283ad9b07d
# Push it to GitHub
git push --set-upstream origin backport-2535-to-release-1.5.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release-1.5.x

Then, create a pull request where the base branch is release-1.5.x and the compare/head branch is backport-2535-to-release-1.5.x.
