    in amplify.yml
    it is because of
    artifacts:
    baseDirectory: "path_is_wrong"

    base directory will start from appRoot that you provided in amplify.yml
    and since it is next base directory’s last folder should be something like "dist/apps/my-app/.next"

    If you use Next.js with { output: "export" } config. Add ‘next export" in package.json

    // package.json
...
"scripts": {
  "dev": "next dev",
  "build": "next build && next export",  // Add next export
  "start": "next start",
  "lint": "next lint"
},
...

    Amplify performs an automatic build based on the "scripts" in package.json.

    next export is deprecated and replaced with "output": "export" since v13.3. However, However, amplify still decides how to build through "next export".
