@gmpinder This affects even the approved PRs, which currently can't get merged and we can't even have a main branch build, let alone a new release containing the fix we need. Is there any chance you have the time to fix this soon-ish? Just asking so we can plan accordingly, cause our setup is blocked by not having that fix included in an available image.
