Describe the issue

Twitter login:

1. Step 1: Construct an Authorize URL. (correct)
2. Step 2: GET oauth2/authorize (correct)

after step 2, twitter redirect to http://localhost:3000/api/auth/callback/twitter?state=xxx&code=xxx

My nextjs console output error:

    code: undefined
  },
  providerId: 'twitter',
  message: 'this.getName is not a function'
}

It seems like a certain field is missing or has an issue when fetching the user information.

How to reproduce

down load https://github.com/mackieq/next-auth-example, config twitter clientId and secret, then:

npm install
npm run dev

Expected behavior

login callback success

[manmohan659]

The original error this.getName is not a function has been resolved with the proper Twitter provider configuration.

Looking at the logs, I can confirm that the Twitter OAuth flow is working correctly and successfully fetching all user data. The logs show:

1. Successful OAuth initiation

2. Complete profile data retrieval

3. Proper token generation and management

4. Working OAuth callback

Here's, something: it's redirecting to sign-in page. The remaining issue is purely a redirect problem after successful authentication. The logs show:

GET /api/auth/callback/twitter?state=[state]&code=[code] 302 GET /login 200

This redirect loop occurs because the app is missing proper session handling. The repository appears to be missing some essential files for NextAuth to work correctly:

• SessionProvider wrapper in the root layout

• Proper session/authentication state handling in components

• NextAuth type definitions

Would you mind confirming if these files are part of the main repo but not included in the next-auth-example repo? If not, they should be added to ensure the complete authentication flow works correctly.

I can submit a PR with these additions if you'd like.
