I recently installed Nextjs v12. I created some Api routes (for example "/api/products"). these routes work correctly, but when I make concurrentFeatures: true in next.config.ts, Api routes don't work. the displayed error in console is error - Error: Cannot find module for page: /api/products

here is my next.config.ts file content:

module.exports = {
  reactStrictMode: true,
  experimental: {
    concurrentFeatures: true
  }
}

here are my directories:

pages
----api
--------products
------------index.ts
