Hi! I really appreciate your youtube video on how to use push notifications with node. But I'm having an issue on client.js line 6 (where it catches errors, so line # is not that helpful)
Error:
DOMException: Subscription failed - no active Service Worker

I believe the service worker is not registered so it can proceed any further. I also tried downloading the code straight from the repo and I'm still getting this error. Thanks in advance!
