The backport to 2.x 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/index-management-dashboards-plugin/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/index-management-dashboards-plugin/backport-2.x
# Create a new branch
git switch --create backport/backport-1031-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 ed98e4ab820ebe7fd436548a4e0793757a4cbb30
# Push it to GitHub
git push --set-upstream origin backport/backport-1031-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/index-management-dashboards-plugin/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-1031-to-2.x.
