Common Issues

OAuth callback fails with ‘invalid redirect URI’
  • Ensure the redirect URI exactly matches what’s configured in your dashboard
  • Check protocol (http vs https) and port numbers
  • For localhost development, use exact port: http://localhost:3000/oauth/callback
Authentication state not updating
  • Verify your OAuth Client UUID is correct for your environment
  • Check that your redirect URI is properly configured
  • Ensure your OAuth client has correct scopes configured
CORS Errors
  • Echo APIs include proper CORS headers
  • Check for proxy or middleware interference
  • Verify request origin matches registered domain
