The backport to 2.17 failed:

The process '/usr/bin/git' failed with exit code 128

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-2.17 2.17
# Navigate to the new working tree
pushd ../.worktrees/backport-2.17
# Create a new branch
git switch --create backport/backport-15703-to-2.17
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 bb0a49758df8380eab748aefeafb5a69ae5cf59f
# Push it to GitHub
git push --set-upstream origin backport/backport-15703-to-2.17
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-2.17

Then, create a pull request where the base branch is 2.17 and the compare/head branch is backport/backport-15703-to-2.17.

Removing the backport 2.17 label, since it was backported manually in #15751
