Oh nice, thanks for this @terryyylim!

I think Fix project argument for feature set describe in CLI would be a better title. The titles are used for our change log so we want them to be human readable.

Also, you need to add a kind label to all PRs. This one requires kind/bug.

@terryyylim Remember to update the release note. Other than that it looks good.
