AddAsync（driveItem）不返回

Question

以下代码中的.AddAsync(driveItem)永不返回。谁能对此有所启发？

IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
    .Create(App.ClientId)
    .Build();

DeviceCodeProvider authProvider = new DeviceCodeProvider(
    publicClientApplication,
    new string[] { "Files.ReadWrite.All" });

GraphServiceClient graphClient = new GraphServiceClient(authProvider);
DriveItem driveItem = new DriveItem
{
    Name = "Foo",
    Folder = new Folder { },
    AdditionalData = new Dictionary<string, object>()
    { { "@microsoft.graph.conflictBehavior", "fail" }
    }
};
await graphClient
    .Me
    .Drive
    .Root
    .Children
    .Request()
    .AddAsync(driveItem);

我尝试使用“ Foo”以外的其他文件夹名称，尝试使用现有或不存在的文件夹的名称均无济于事。

我也尝试对“ @ microsoft.graph.conflictBehavior”使用“重命名”而不是“失败”。

我也尝试了没有AdditionalData的尝试。[编辑2]我决定等待该方法返回一段时间（超过10分钟），它最终引发了异常：

代码：generalException消息：发送请求时发生错误。

以下代码具有完全相同的问题：

IDriveItemChildrenCollectionPage children = await graphClient.Me.Drive.Root.Children
    .Request()
    .GetAsync();

这似乎是Graph SDK的一般问题。

我进行了Azure Active Directory的应用程序注册，并获得了以下最内部的例外：

AADSTS70000: The provided value for the input parameter 'device_code' is not valid.

同样，我必须等待10分钟以上才能引发异常。

我不确定为什么不返回，但是Camera Roll是special folders之一（因此是保留的文件夹名称）。在配置Drive或第一次连接特定服务时（即由OneDrive应用创建“相机胶卷”）时，会自动生成其中的少数几个：

• 文档
• 照片
• 相机胶卷
• 应用根目录
• 音乐

为了检索“相机胶卷”文件夹，请通过其“ id”进行请求：

GET /me/drive/special/cameraroll
