The backport to release-v3 failed:

The process '/usr/bin/git' failed with exit code 1

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-release-v3 release-v3
# Navigate to the new working tree
cd .worktrees/backport-release-v3
# Create a new branch
git switch --create backport-3286-to-release-v3
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 a8f22f7e07370d4700dc039db5b69654c2798042
# Push it to GitHub
git push --set-upstream origin backport-3286-to-release-v3
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-release-v3

Then, create a pull request where the base branch is release-v3 and the compare/head branch is backport-3286-to-release-v3.
