Postman Microsoft Graph Beta通道API在创建专用通道时出现500错误

直到昨天，我还能够通过Beta Channel API创建私人频道。今天突然出现了500个错误（内部服务器错误）。我在头中传递令牌，Json也正确传递。 有没有人也面临同样的问题

我在Postman中执行的API

{
 "@odata.type": "#Microsoft.Teams.Core.channel",
 "membershipType": "private",
 "displayName": "My First Private Channel",
 "description": "This is my first private channels",
 "members":
    [
       {
          "@odata.type":"#microsoft.graph.aadUserConversationMember",
          "user@odata.bind":"https://graph.microsoft.com/beta/users('92fb4ef2-3ad8-4316-a6f2-2925afcb7d75')",
          "roles":["owner"]
       }
    ]
}
