Describe the bug

We have a Next.js v15 app deployed to vercel and it works well. Now we want to deploy the exactly same code to AWS Amplify instead. But when we tried to create new app, Amplify cannot detect the correct framework.

Below are screenshots taken while creating the app.

And package.json under packages/ops2-web-app is as below

{
  "private": true,
  "scripts": {
    "build": "next build",
    "dev": "next dev --turbo",
    "start": "next start"
  },
  "dependencies": {
    "@heroicons/react": "^2.1.4",
    "@radix-ui/react-dropdown-menu": "^2.1.2",

  },
  "devDependencies": {

    "@types/node": "20.14.8",
    "@types/pg": "^8.6.6",
    "tailwindcss-animate": "^1.0.7"
  }
}

Can anyone shred some light on what could be wrong here?

Thanks!
