Q: will the results contain object without workspaces field?

[Hailong-am]

Base on current implementation, it won't.

The backport to workspace 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-Dashboards/backport-workspace workspace
# Navigate to the new working tree
pushd ../.worktrees/OpenSearch-Dashboards/backport-workspace
# Create a new branch
git switch --create backport/backport-216-to-workspace
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 77738118758626f30aa8ae5517e25e739a884cbd
# Push it to GitHub
git push --set-upstream origin backport/backport-216-to-workspace
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/OpenSearch-Dashboards/backport-workspace

Then, create a pull request where the base branch is workspace and the compare/head branch is backport/backport-216-to-workspace.
