I tried running the repo, but got

Line must be greater than or equal to 1, got -1

I think there are still issues with the Firebase 9 SDK - if you pin it to the 9.0.0 version it works.

That worked, thanks!

I had this same issue, which brought me here. I later found Ben McCann's comment in the Firebase SDK queue. Adding the suggested config to svelte.config.js seems to solve the problems with firebase/auth. PR seems hardly worth the trouble but I think this is the workaround for now.
