"serviceworker" must be a dictionary in your web app manifest

I am trying to integrate Razorpay subscriptions.

I am using NodeJs as Backend and React for Frontend.

Manifest.json looks like this -

{
  "short_name": "React App",
  "name": "Create React App Sample",
  "icons": [
    {
      "src": "favicon.ico",
      "sizes": "64x64 32x32 24x24 16x16",
      "type": "image/x-icon"
    },
    {
      "src": "logo192.png",
      "type": "image/png",
      "sizes": "192x192"
    },
    {
      "src": "logo512.png",
      "type": "image/png",
      "sizes": "512x512"
    }
  ],
  "start_url": ".",
  "display": "standalone",
  "theme_color": "#000000",
  "background_color": "#ffffff",
}

The error comes up whenever I click pay button, and I guess due to this Razorpay is not considering the order as Subscription.

Update : I raised a query on Razorpay portal and received the following reply.
