The Redirect Loop

Description

GitHub OAuth login appears to succeed — exchangeCodeForSession returns no error and data.user is populated. The callback redirects to /dashboard. But the dashboard always redirects back to /api/auth/signin because getCurrentUser returns null.


Vercel logs show the loop clearly:

GET /api/auth/callback  → 302 /dashboard
GET /dashboard          → 302 /api/auth/signin
GET /api/auth/signin    → 302 github.com
(repeat)

The users table has these RLS policies: SELECT USING (true) and UPDATE USING (auth.uid()::text = id::text). There is no INSERT policy — but adding one alone won't fix it.


On which line number is the incorrect Supabase client used for the database write?

Input Data

1  // src/pages/api/auth/callback.ts
2  import type { APIRoute } from 'astro';
3  import { createServerClient } from '@supabase/ssr';
4  import { supabase } from '../../../lib/supabase'; // anon key, no session context
5  
6  export const GET: APIRoute = async ({ url, cookies, redirect }) => {
7    const code = url.searchParams.get('code');
8    if (!code) return redirect('/');
9  
10   const client = createServerClient(SUPABASE_URL, SUPABASE_ANON_KEY, {
11     cookies: {
12       getAll: () => getCookies(cookies),
13       setAll: (cs) => setCookies(cookies, cs),
14     },
15   });
16 
17   const { data, error } = await client.auth.exchangeCodeForSession(code);
18   if (error || !data.user) return redirect('/?auth=error');
19 
20   const githubId  = parseInt(data.user.user_metadata?.provider_id);
21   const githubLogin = data.user.user_metadata?.user_name;
22 
23   await supabase.from('users').upsert({
24     github_id: githubId,
25     github_login: githubLogin,
26   }, { onConflict: 'github_id' });
27 
28   return redirect('/dashboard');
29 };
