为多个用户订阅 MS Graph API 中的状态

Question

我目前正在尝试通过 MS Graph API SDK (Beta) 检索 Teams 状态信息。仅订阅某些用户时，一切都运行顺利。一旦用户数量变大，问题就开始了。我希望有人能澄清一下：

基本上我是按照上面提到的那样做的 here:

Subscription = Client.Subscriptions.Request().AddAsync(new Subscription
{
   Resource = $"/communications/presences?$filter=id in ('<guid>','<guid>',...))",
   ChangeType = "updated",
   ...
}).Result

问题 1：两个订阅，每个 user/presence

一切正常后，我尝试创建多个订阅。在我的测试案例中，有两个订阅，每个订阅都有一个联系人。尝试创建第二个订阅无效并出现错误 "Operation: Create; Exception: [Status Code: Conflict; Reason: A subscription already exists. It must be deleted before a another can be made.]" 我现在想知道我是否做错了什么或者这是一个限制（没有在文档中找到任何内容）。我希望我做错了什么，因为目标是监控比上面链接文章中提到的 650 名用户更多的用户。我得到的错误：

Code: ExtensionError
Message: Operation: Create; Exception: [Status Code: Conflict; Reason: A subscripton already exists. It must be deleted before a another can be made.]
Inner error:
    AdditionalData:

ClientRequestId: 9d45a16b-9cac-4515-92f9-b81b36318189

问题 2：一个订阅，多个 users/presences

之后，我尝试为超过三个测试用户创建一个订阅，遗憾的是它也没有按预期工作：

250 Users/presences

Code: ExtensionError
Message: Operation: Create; Exception: [A task was canceled.]
Inner error:

650 Users/presences

Code: UnknownError
Message: The page was not displayed because the request entity is too large.
Inner error:

有人知道这里出了什么问题吗？任何信息都会有所帮助。

Answer 1

当我们尝试添加更多订阅时，我们会收到冲突错误“订阅已存在。必须先删除它才能创建另一个订阅”，因为它只支持一个订阅。
