I am running npm run dev in my NextJS project in Codespaces. However, the port is not being forwarded and when I try to manually forward the port, Codespaces says "activating extensions" and does nothing.

Hey,

First check "package.json"

Should look like this:

"scripts": {
  "dev": "next dev"
}

Next make sure your Next.js configuration allows for connections from all interfaces

module.exports = {
  devIndicators: {
    autoPrerender: false,
  },
  serverRuntimeConfig: {
    host: '0.0.0.0',
  },
};

Also this modification in your package.json could help:

"scripts": {
  "dev": "next dev -p 3000 -H 0.0.0.0"
}

Let me know if that works, David.
