Bolt auth

OAuth2 Provider Not Configured - Missing Client ID

Your OAuth2 provider (Google, GitHub, Facebook) authentication fails immediately with cryptic errors. The login redirect works but authorization fails.

Common signs: blank page on OAuth callback, 'client_id not found' in browser console, or authentication loops indefinitely.

Error Messages You Might See

Error: client_id is undefined AuthenticationError: OAuth provider returned invalid_request 401 Unauthorized: Missing authentication credentials
Error: client_id is undefinedAuthenticationError: OAuth provider returned invalid_request401 Unauthorized: Missing authentication credentials

Common Causes

  1. Environment variable for OAuth client ID is undefined or mistyped
  2. Redirect URI registered with provider doesn't match application URI
  3. OAuth credentials copied incorrectly from provider dashboard
  4. Mixed up client ID and client secret values
  5. Development vs production configuration mismatch

How to Fix It

Verify environment variables are loaded: console.log(process.env.NEXT_PUBLIC_OAUTH_CLIENT_ID)

Check OAuth provider dashboard (Google Cloud Console, GitHub Settings) - ensure 'Authorized redirect URIs' includes your Bolt app URL.

Validate the redirect URI format matches exactly: https://your-app.bolt.new/api/auth/callback

Frequently Asked Questions

Where do I find OAuth credentials?

Visit your OAuth provider's developer dashboard. For Google: console.cloud.google.com. For GitHub: github.com/settings/developers

What's the correct redirect URI format?

Use https://your-app-name.bolt.new/api/auth/callback for Bolt deployments

Can I test OAuth locally?

Yes, but use localhost:3000/api/auth/callback in your provider settings, then switch to production URI before deploying
