rest - ご安心ください - ResponseSpecBuilder を使用すると、抽出された応答が空になります

Question

私が削除した場合

.spec(応答仕様)

私の呼び出しから、応答は「FOO」で正常に出力されます。ビルダーを含めると、(テストに合格していても) 応答に空の文字列が出力されます。誰でも理由、またはこれを修正する方法を知っていますか? ビルダーを使用して、合格したテストの応答を出力したいと思います。

public void getCirclesId()
    {
        String endpoint = "getCirclesId";
        String url = baseUrl + resourcePath + "/" + circleId;
        RequestSpecification given = given().header("Authorization", RestTest.BEARER_TOKEN);

        ResponseSpecBuilder specBuilder = new ResponseSpecBuilder();
        specBuilder.expectBody("features.priceMonth", is("5.00"));
        specBuilder.expectBody("features.priceYear", is("50.00"));
        Response response = JsonTest.executeRequestWithSpec(given, url, resource, endpoint, JsonTest.HttpType.GET, specBuilder);
    }
