The error is still about the missing secret. However, I notice the issue might be that the secret isn't being properly recognized. Let me check if there's an environment variable setup issue or if the secret needs to be added differently:

Good! The auth.ts file is properly configured with the secret. Now I see the issue - the app/page.tsx is trying to use Prisma directly, but Prisma won't work in the v0 preview environment. I need to make the page work without the database for preview and gracefully handle the Prisma initialization error. Let me fix this:

Configurei a página inicial para funcionar no preview do v0 usando dados de exemplo como fallback quando o Prisma não está disponível. O código tenta conectar ao banco de dados, mas graciosamente volta aos produtos de amostra em caso de erro, permitindo que a vitrine seja visualizada mesmo sem a conexão com o banco. Em produção, o banco será usado normalmente.

Good! I can see that authConfig is correctly exported as a named export on line 3. The file is correct. Now let me verify that it's being imported correctly in auth.ts:

The authConfig is correctly:

• Exported in auth.config.ts as a named export (line 3: export const authConfig = {...})
• Imported in both auth.ts and proxy.ts using the correct named import pattern

The diagnostic error appears to be a false positive from the v0 system. The code structure is correct. This is likely a caching or build issue. The file exports exactly what's being imported - authConfig as a named export that satisfies NextAuthConfig.

You can proceed with testing the application. The auth configuration is properly set up and should work once the preview reloads or the build cache is cleared.
