c# - Microsoft.Graph.GraphServiceClient Planner Buckets AddAsync 返回错误 "Write requests are only supported on contained entities"

Question

我有一些代码可以获取或创建 Planner Bucket .

public async Task<PlannerBucket> GetOrCreateBucket(GraphServiceClient graphServiceClient, string planId, string name)
{
    var buckets = await graphServiceClient
        .Planner
        .Plans[planId]
        .Buckets
        .Request()
        .GetAsync();

    var bucket = buckets.SingleOrDefault(b => b.Name.Equals(name));

    if (bucket == null)
    {
        bucket = await graphServiceClient
            .Planner
            .Plans[planId]
            .Buckets
            .Request()
            .AddAsync(new PlannerBucket()
            {
                Name = name
            });
    }

    return bucket;
}

一年前最初编写这段代码时，我相当确定它工作正常。

早期经常有新的 buckets 并且创建的很好。从那以后创建代码很少被调用，最近调用它时返回错误:

Microsoft.Graph.ServiceException: Code: BadRequest
Message: Write requests are only supported on contained entities

我不太确定这个错误是什么意思。

实体被收容是什么意思？
为什么不包含它？
它甚至意味着哪个实体？
这是否意味着我正在尝试创建的存储桶？
这是否意味着我试图在其中创建它的计划？

这些问题的答案会很好，因为它们可以帮助我理解如何解决问题，但归根结底，真正的问题是:“我做错了什么，我该如何纠正？”。

这是 HTTP 请求:

搜索了一下，我认为这个问题已经在 github 上报告过，但目前仍未解决:https://github.com/microsoftgraph/msgraph-sdk-dotnet/issues/307

此处的错误消息不是很有用，但问题是我们不允许 POST 到 planner/plans/planid/buckets。您应该将请求发送到 planner/buckets 并在请求正文中包含 planid 属性。文档中的示例是准确的(顺序提示是可选的):https://learn.microsoft.com/en-us/graph/api/planner-post-buckets?view=graph-rest-1.0
