Site cannot be installed: icon downloaded from the manifest was empty or corrupted

I'm getting the error

Site cannot be installed: icon downloaded from the manifest was empty or corrupted

I'm not able to find what is the problem. Below is my manifest.json. I'm using Angular 4 Progressive web app with material design.

As stated in this document - Customize the icons, when placing the src path of the icon, it must refer to the root directory. You should change the path by removing / at the beginning and compile it again.

"icons": [{
    "src": "images/touch/icon-128x128.png",
    "type": "image/png",
    "sizes": "128x128"
  }, {
    "src": "images/touch/apple-touch-icon.png",
    "type": "image/png",
    "sizes": "152x152"
  }, {
    "src": "images/touch/ms-touch-icon-144x144-precomposed.png",
    "type": "image/png",
    "sizes": "144x144"
  }, {
    "src": "images/touch/chrome-touch-icon-192x192.png",
    "type": "image/png",
    "sizes": "192x192"
  }],
