Current vs Expected behavior: I completed all 16 chapters of the Next.js dashboard course. When I click "Sign in to save progress" on any chapter page I am redirected to nextjs.org/auth/error with a 404 page. Expected behavior is to be taken to a sign in page and then have my progress saved so I can claim my completion certificate.

Code, configuration, and steps to reproduce: Go to nextjs.org/learn/dashboard-app/next-steps Click "Sign in to save progress" Redirected to nextjs.org/auth/error — 404 page Tried with Chrome and Safari browsers Tried signing in with both GitHub and email All methods result in the same 404
