I I didn't find the repo of Airlock. In the course Side Quest: Authentication & Authorization

The course provided me with this link. But this link leads to a 404 . error
git clone GitHub - apollographql-education/side-quest-auth

Whoops, good catch! Looks like it was an issue with that repo’s visibility settings. I’ve updated them to make it public, so you should be able to access it now!

Thanks for reaching out!

Wonderful, this repo is visible now
