The file looks correct. The error message is showing line 9 which points to the old code, so it's likely showing cached/stale errors. Let me also check the main middleware.ts file to ensure it's correct:

Both files look correct. The error in the stack trace is showing old line numbers (line 9) but my fix moved the createServerClient call to line 18. Let me force a refresh by making a small whitespace change to trigger a rebuild:

The middleware file already has the fix in place - it checks for the Supabase environment variables before attempting to create the client, and returns early if they're not configured. The error you're seeing is from a cached/stale build. The small quote change I just made should trigger a fresh rebuild that picks up the correct code with the environment variable check on lines 10-16.

Now let me also fix the sidebar which uses the same icon:

Fixed the icon issue. The Bridge icon doesn't exist in lucide-react, so I replaced it with CloudSun which fits the "SkyBridge" brand better (combining sky and connection themes). Updated both the navbar and sidebar components to use the correct icon.

OK. I see two problems:

1. Navbar still has Bridge import - my earlier fix didn't stick, the file still shows Bridge on line 5.
2. 404 on auth routes - the links point to /auth/login and /auth/register, but the actual pages live at app/(auth)/login/ and app/(auth)/register/ which means their routes are /login and /register (the (auth) group is a route group that does NOT add a URL segment).

Let me verify and fix both:

OK. The navbar icon is already fixed (CloudSun). The logs are stale from before my fix. The real remaining issue is the 404 on auth routes: the pages exist at app/(auth)/login/page.tsx and app/(auth)/register/page.tsx -- the (auth) parentheses mean it's a route group, so the actual URL is /login and /register, NOT /auth/login and /auth/register. All links currently point to /auth/login and /auth/register which don't exist.

Let me fix every link across the app:

Now I can see the problem clearly. The auth pages live at app/(auth)/login/ and app/(auth)/register/ -- the (auth) folder is a route group, so the URLs are /login and /register. But all links point to /auth/login and /auth/register which don't exist. Let me fix every file:

The root cause was that (auth) is a Next.js route group -- the parentheses mean the folder name is NOT part of the URL. So app/(auth)/login/page.tsx maps to /login, not /auth/login. I fixed all 5 files (landing page, navbar, register, sign-up-success, and middleware) to use the correct paths: /login, /register, and /sign-up-success.
