在Microsoft Teams Channel中创建在线会议，以在响应中返回空参与者的数组

Question

我正在使用此端点并将此请求数据发送到JSON formate中的正文中

端点-https://graph.microsoft.com/beta/app/onlineMeetings

请求正文-

{
    "startDateTime":"2019-12-29T14:30:34.2444915Z",
    "endDateTime":"2040-12-21T14:30:34.2444915Z",
    "subject":"Team Meeting",
    "participants": {
        "organizer": {
            "identity": {
                "user": {
                   "id":"{registered user email id}"
                }
             }
        },
        "attendees": [{
            "identity": {
                "user": {
                    "id":"{registered user email id}"
                }
            }
        }]
    },
    "chatInfo":{
        "threadId":"{threadId}"
    }
}

有人可以让我知道为什么我得到一个空的与会者数组吗？
