Microsoft Graph API-400上载大文件时出错

我正在尝试使用Graph API在Sharepoint中上载一个大文件（超过5 MB）。 我已经正确地创建了上传会话url（我想，我已经获得了一个看起来不错的url），但是当我尝试使用这个上传url上传我的文件时，我得到了一个400错误的请求错误

这是我的密码：

HttpClient uploadRequestClient = new HttpClient();
var uploadRequestContent = new ByteArrayContent(byteContent);
var uploadResponse = await uploadRequestClient.PutAsync(uploadUrl, uploadRequestContent);

以下是回应：
