Steps to reproduce

1. Create vue.config.js file with this content:

'use strict';

module.exports = {
    devServer: {
        port: 8087,
    },
    pwa: {
        icons: [
            {
                'src': 'icons/android-chrome-192x192.png',
                'sizes': '192x192',
                'type': 'image/png',
            },
            {
                'src': 'icons/android-chrome-512x512.png',
                'sizes': '512x512',
                'type': 'image/png',
            },
        ],
        iconPaths: {
            favicon32: 'icons/favicon-32x32.png',
            favicon16: 'icons/favicon-16x16.png',
            appleTouchIcon: 'icons/apple-touch-icon-180x180.png',
            maskIcon: 'icons/safari-pinned-tab.svg',
            msTileImage: 'icons/mstile-144x144.png',
        }
    }
};

1. Run yarn serve

What is expected?

The icons in the manifest should be the same path you entered in the config file.

What is actually happening?

The icons that used are the default. https://github.com/vuejs/vue-cli/blob/dev/packages/%40vue/cli-plugin-pwa/lib/HtmlPwaPlugin.js#L15

Chrome debugger: Error while trying to use the following icon from the Manifest: http://localhost:8087/img/icons/android-chrome-192x192.png (Download error or resource isn’t a valid image)
