[Bhargavasrinivas]

Hi I need to add some custom attributes to Products while checkout , here i need to pass Gift Wrap option as a Custom attribute , Below is my code snippate

private List attributvalue = new ArrayList<>(); attributvalue.add(new Storefront.AttributeInput("Gift Wrap", "Yes") );

input = new Storefront.CheckoutCreateInput() .setLineItemsInput(Input.value(datalist) ).setCustomAttributesInput(Input.value(attributvalue));

    Storefront.MutationQuery query = Storefront.mutation(mutationQuery -> mutationQuery
            .checkoutCreate(input, createPayloadQuery -> createPayloadQuery
                    .checkout(checkoutQuery -> checkoutQuery
                            .webUrl()
                            .totalPrice()
                            .subtotalPrice()

                    )
                    .userErrors(userErrorQuery -> userErrorQuery
                            .field()
                            .message()
                    )
            )
    );

if you are processing checkout through StoreFrontApi, can you please share your code with me? I am getting an error on Polling for shipping rates gives error "Failed to reschedule GraphQL query execution". And I havn't found a correct solution.
