getNode is not present in Pooling Shipping Rate RetryHander API : v3.2.3

[ashu2121]

Hello I m new in GraphQL.

I have implemented library version: 3.2.3 in my project. I m trying to get shipping rate from api to display, code start giving me compile time error. I m using pooling shipping rate api.

RetryHandler.exponentialBackoff(800, TimeUnit.MILLISECONDS, 1.2f)
                        .whenResponse(
                                response -> ((Storefront.Checkout)response.data().getNode()).getAvailableShippingRates().getReady() == false
                        )
                        .maxCount(12)
                        .build()`

But `getNode` is not present i tried all the way to retrieve `getNode`. Here is full code

`graphClient.queryGraph(query).enqueue(
                new GraphCall.Callback<Storefront.QueryRoot>() {
                    @Override public void onResponse(@NonNull final GraphResponse<Storefront.QueryRoot> response) {
                        Storefront.Checkout checkout = (Storefront.Checkout) response.data().getNode();
                        List<Storefront.ShippingRate> shippingRates = checkout.getAvailableShippingRates().getShippingRates();
                        for(int i = 0; i<shippingRates.size();i++) {
                            Log.d(TAG, "shippingRates getPrice => " + shippingRates.get(i).getPrice());
                            Log.d(TAG, "shippingRates getTitle => " + shippingRates.get(i).getTitle());
                        }
                    }

                    @Override public void onFailure(@NonNull final GraphError error) {
                    }
                },
                null,
                RetryHandler.exponentialBackoff(800, TimeUnit.MILLISECONDS, 1.2f)
                        .whenResponse(
                                response -> ((Storefront.Checkout)response.data().getNode()).getAvailableShippingRates().getReady() == false
                        )
                        .maxCount(12)
                        .build()
         );

can anyone guide me on how to use a retry handler in pooling shipping rate api. Althuogh i can make another retry handler using this library. but it will cost resources and battery. Better i want to use a built-in retry handler.

thanks in advance

i tried changing the code like below to get getNode()

 RetryHandler.exponentialBackoff(800, TimeUnit.MILLISECONDS, 1.2f)
      .whenResponse(
                 response -> ((Storefront.Checkout) ((GraphResponse<Storefront.QueryRoot>)response).data().getNode()).getAvailableShippingRates().getReady() == false)
      .maxCount(100)
      .build()

But i m getting error Failed to execute GraphQL request, getNode on null reference. Do anyone guide me what i m doing wrong?

thanks in advance.

actually getNode present in version 3.2.3. that's why i had to update the version to newer. Now everything works great. thanks
