The backport to 3.1 failed:

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

To backport manually, run these commands in your terminal:

# Navigate to the root of your repository
cd $(git rev-parse --show-toplevel)
# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/OpenSearch/backport-3.1 3.1
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch/backport-3.1
# Create a new branch
git switch --create backport/backport-18542-to-3.1
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 a7f28f646775b0ce7066fec3d9a5d67f00485e2b
# Push it to GitHub
git push --set-upstream origin backport/backport-18542-to-3.1
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch/backport-3.1

Then, create a pull request where the base branch is 3.1 and the compare/head branch is backport/backport-18542-to-3.1.

Created backport here: #18543

Commit 674de10 was not backported to 3.1, so the cherry-pick failed. I created the backport by just reverting the one commit from 3.1.
