Microsoft graph api 使用图形API在Sharepoint中创建文件夹时出错

我试图在Sharepoint中创建子文件夹，但收到错误。我可以成功创建两个级别的文件夹，但在创建第三个级别时，我收到以下错误：

请求URI无效。绑定到“microsoft.graph.driveItem”的绑定函数不支持转义函数批注

我正在使用Postman并按以下步骤创建文件夹：

1顶层：成功-已创建文件夹1

2第一个子项成功-在Folder1中创建Folder2

第二个孩子失败了

---

对于如何正确创建Folder3文件夹的任何反馈，我们将不胜感激。

在最后一个示例中，由于为访问提供的端点中的Folder2指定了无效的Url格式，因此会出现错误：

    https://graph.microsoft.com/v1.0/sites/<SITE_ID>/drive/root:/Folder1:/Folder2:/children
                                                                |_________________|                                                          
                                                                       ^^^
                                                          invalid path syntax for accessing Folder2
