The backport to maintenance/2.17.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-maintenance/2.17.x maintenance/2.17.x
# Navigate to the new working tree
cd .worktrees/backport-maintenance/2.17.x
# Create a new branch
git switch --create backport-8530-to-maintenance/2.17.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 08742dbea32edc54aa27dbcbaecdf3532a8e15ae
# Push it to GitHub
git push --set-upstream origin backport-8530-to-maintenance/2.17.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-maintenance/2.17.x

Then, create a pull request where the base branch is maintenance/2.17.x and the compare/head branch is backport-8530-to-maintenance/2.17.x.
