manifest display property must be one of 'standalone', 'fullscreen', or 'minimal-ui' when display: 'standalone' is in options

I have my webpack config for WebpackPwaManifest as the code below, but am still getting manifest display property must be one of 'standalone', 'fullscreen', or 'minimal-ui' under Application in the browser

const WebpackPwaManifest = require("webpack-pwa-manifest");
...
module.exports = {
...
  plugins: [
  ...
    new WebpackPwaManifest({
      icons: [
        {
          src: path.resolve("src/assets/images/Favicon/android-chrome-192x192Circle.png"),
          sizes: "192x192",
          type: "image/png",
        },
        {
          src: path.resolve("src/assets/images/logo/icon-512x512.png"),
          sizes: "512x512",
          type: "image/png",
        },
      ],
      name: "example",
      short_name: "example",
      orientation: "portrait",
      // display: 'standalone',
      start_url: "http://localhost:8080",
      theme_color: "#96cbbf",
      background_color: "#ffffff",
      description: "Description",
      display: "browser", //property set to fullscreen, standalone, or minimal-ui
      prefer_related_applications: false, //Says if you would prefer that the user download a mobile app from the app store or something
    })
    ...
   ]
}

The mistake was that I had display in there twice
