  "build": {
    "app-bundle-id": "com.datafiniti",
    "app-category-type": "public.app-category.visual-scraper",
    "iconUrl": "build/icon.ico"
  },

  "scripts": {
    "postinstall": "install-app-deps",
    "pack": "build --platform=all",
    "dist:win": "build --platform=win32"
  }

when running npm run dist:win i run into the following error:
