Not able to checkout status - Ready() status

[gowtham-me]

We are trying to get checkout callback for WebCheckout. For that, we need Checkout status.

I am using the below code to get checkout statue - Ready() `Polling for checkout completion ⤴ After a successful checkoutCompleteWith... mutation, the checkout process starts. This process is usually short, but it isn't immediate. Because of this, polling is required to obtain an updated checkout in a ready state - with a Storefront.Order.

GraphClient client = ...;
ID paymentId = ...;

Storefront.QueryRootQuery query = Storefront.query(rootQuery -> rootQuery
    .node(paymentId, nodeQuery -> nodeQuery
        .onPayment(paymentQuery -> paymentQuery
        .checkout(checkoutQuery -> checkoutQuery
                    .ready()
            .order(orderQuery -> orderQuery
            .processedAt()
            .orderNumber()
            .totalPrice()))
        .errorMessage()
        .ready()
        )
    )
);

client.queryGraph(query).enqueue(
  new GraphCall.Callback<Storefront.QueryRoot>() {
    @Override public void onResponse(@NonNull GraphResponse<Storefront.QueryRoot> response) {

         Storefront.Payment payment = (Storefront.Payment) response.data().getNode();

         if (payment.getErrorMessage() == null || payment.getErrorMessage().isEmpty()){
        Storefront.Checkout checkout = payment.getCheckout();
        String orderId = checkout.getOrder().getId().toString();
                Boolean status = checkout.getReady();
         }
         else{
        String errorMessage = payment.getErrorMessage();
         }

    }
    @Override public void onFailure(@NonNull GraphError error) {
    }
  },
  null,
  RetryHandler.exponentialBackoff(500, TimeUnit.MILLISECONDS, 1.2f)
    .whenResponse(
      response -> ((Storefront.Payment) ((GraphResponse<Storefront.QueryRoot>) response).data().getNode()).getReady() == false
    )
    .maxCount(12)
    .build()
);

I am getting NULL as a response for checkout.
