@tkoyama010 I believe there has been a major syntax change in the API ... I might try to convert to the new format, rather than go back to version v4.

Hang tight and let me investigate 👍

@bjlittle Yes, I modified the label.yml to the new writing style, but an error occurred. Please let me know if you can resolve this issue. If we can't solve it, let's merge this, and see how other projects solve it for a while.
