Question

我正在尝试使用GCP的Cloud Asset API并获取其中一台VM的历史记录。我尝试在API Explorer和Java代码上都使用BatchGetAssetsHistoryRequest，但是响应始终为空。我只是不知道我调用此API的方式是否有问题，或者Asset API根本不能用于此目的。

我已启用Cloud Asset API，但没有任何身份验证问题。我要查询的资源也存在

            }

        }
        System.out.println("Testing");
    }
}

不管我设置的开始时间如何，BatchAssetsHistoryResponse始终为空。
