The backport to 7.69.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-7.69.x 7.69.x
# Navigate to the new working tree
cd .worktrees/backport-7.69.x
# Create a new branch
git switch --create backport-20735-to-7.69.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 f33c677a2fcf68a1ebc73e0c5c5c4f9c68399ae6
# Push it to GitHub
git push --set-upstream origin backport-20735-to-7.69.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-7.69.x

Then, create a pull request where the base branch is 7.69.x and the compare/head branch is backport-20735-to-7.69.x.
