The backport to v6.x 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-v6.x v6.x # Navigate to the new working tree cd .worktrees/backport-v6.x # Create a new branch git switch --create backport-3551-to-v6.x # Cherry-pick the merged commit of this pull request and resolve the conflicts git cherry-pick -x --mainline 1 a6dac3149c505b58d2e6d068b97f4dc993da55f0 # Push it to GitHub git push --set-upstream origin backport-3551-to-v6.x # Go back to the original working tree cd ../.. # Delete the working tree git worktree remove .worktrees/backport-v6.x

Then, create a pull request where the base branch is v6.x and the compare/head branch is backport-3551-to-v6.x.
