The previous cherry-pick is now empty, possibly due to conflict resolution.
If you wish to commit it anyway, use:

    git commit --allow-empty

Otherwise, please use 'git cherry-pick --skip'

nothing to commit, working tree clean

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-12.4 12.4
# Navigate to the new working tree
cd .worktrees/backport-12.4
# Create a new branch
git switch --create backport-357-to-12.4
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 14ccacd617b99a9c17d4c709b216a1943820ddad,ae31f86b455f6c460c3fd475ebd6f24d9e3eaf5c,c1962145fe5834f05132d864d7257d7fd87ac3c7,f04fc9176f5063febb331bf5899a18c693602af8,1728ff77624c67585c991c786c557573570f7fb9,c2d6cbd409fe11cb2670e551b441ca9ccbf0ba05,572b2948b6184d8a3d7c98d2feacfff44b3d9061,c944ed3205fccfca7a6748669f88d9e43d424087,87af7321182c0e72858fa29687eed6e14b93fe23,c0422bea650dca88c16e73093256c9fdbdaf3ffa,0267e29f0cd49bf95f0d2d3b4460ac0ccd10bf24,45e5a49b131bf4289869d09f8cc8f707fc3aa767,85b50d477ad48ef1268379b390ac366f0a1fccb5,1cc0613f5ea2b997dc50f8cc54a56508de4ae083
# Push it to GitHub
git push --set-upstream origin backport-357-to-12.4
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-12.4

Then, create a pull request where the base branch is 12.4 and the compare/head branch is backport-357-to-12.4.

(Manually backported directly to 12.4, it applied clean)
