static+vercel: "r is not defined" | Astro Lounge | Page 1

I'm getting a cryptic "r is not defined" error when deploying a static build on vercel. It works fine on local, and it was working just fine like 2 days ago.

ReferenceError: r is not defined

I've tried to redeploy an old commit that was working fine 2 days ago, but it fails as well
