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:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add ../.worktrees/backport-2.x 2.x
# Navigate to the new working tree
pushd ../.worktrees/backport-2.x
# Create a new branch
git switch --create backport/backport-495-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 004bb9595f21ecccea6914c050513aaad13d6612
# Push it to GitHub
git push --set-upstream origin backport/backport-495-to-2.x
# Go back to the original working tree
popd
# Delete the working tree
git worktree remove ../.worktrees/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-495-to-2.x.

@chenqi0805 seems like we need a manual backport to 2.x, would you take it please?

[chenqi0805]

@reta I can try that. Could you also review the other related PR? #493

[chenqi0805]

@reta Can you help me with manual backport? I got

git fetch
git worktree add ../.worktrees/backport-2.x 2.x
fatal: invalid reference: 2.x

@chenqi0805 It shows that you don't have a local 2.x branch. You can either checkout a 2.x branch on your local or use the branch from upstream. Example:

git fetch
git worktree add ../.worktrees/backport-2.x upstream/2.x

Thanks @VachaShah , @chenqi0805 if you still have difficulties, I could do backport for you, thank you
