Network error: Unable to connect to the server. This could be due to CORS restrictions, the server being down, or network connectivity issues. Request Details: Method: GET URL: Nextjs App deployed on vercel Header: Using Deployment protection bypass secret But on executing the same request on postman, responds successfully.

Try adding CORS headers to your Next.js API route to resolve the network error.
For example, in your API handler, add:

export default function handler(req, res) {
  res.setHeader('Access-Control-Allow-Origin', '*');
  // ...your existing logic
  res.status(200).json({ message: 'Thank You' });
}

export default function handler(req, res) {
  res.setHeader('Access-Control-Allow-Origin', '*');
  // ...your existing logic
  res.status(200).json({ message: 'Thank You' });
}

This allows cross-origin requests and should fix CORS-related network errors when called from the API Request Tool. Source: - Server URLs Vapi Documentation
