biz.cspace.saveFile调用失败

钉钉已经申请该权限：
dd.config($.extend(
true,
                            {
                                appId: '',
                                corpId: window.ding['corpId'],
                                jsApiList: [
                                        'biz.cspace.saveFile', //盯盘存储
                                        'biz.cspace.preview' //盯盘预览
                                ]
                            },
                            ret['data']
                        ));然而调用存储接口，仍然提示错误，代码如下：
dd.biz.cspace.saveFile({
                        corpId:window.ding['corpId'],
                        url: file_long,
                        name:"文件预览123",
                        onSuccess: function(data) {
  console.log('上传成功：',data);
                        },
                        onFail: function(err) {
  console.log('失败：',err);
                        }
                    });
onFail回调返回如下：
失败： Object {errorCode: 7, errorMessage: "requestJsApis() not invoked"}
