图形 API 设置共享点联机权限失败

Question

我们有一个系统，该系统使用后台服务来设置使用 .Net Graph SDK 对新创建的 SharePoint Online 文档的权限。 看似随机的，我们的操作失败并出现 UnknownError 响应，我们不确定从那里开始。

我们尝试按需重现该问题，但我们仅在非交互式后台服务上遇到该问题。 后台服务执行此操作的次数比我们尝试按需执行的次数要多得多，因此在这种情况下，此操作发生得更多是有道理的。

var driveRecipients = new List<DriveRecipient>();
// Code that adds recipients
// var recipient = new DriveRecipient { Email = "..." };
// driveRecipients.Add(recipient)
var roles = new List<string> { "write" };
var inviteResult = await graphClient
.Drives[driveId]
.Items[fileId]
.Invite(driveRecipients, true, roles, notifyUsers, "Automated SharePoint permission added by app X")
.Request().PostAsync(cancellationToken);
return inviteResult;

通常，我们会收到 IDriveItemInviteCollectionPage 结果，但是当发生错误时，会抛出类似于以下内容的异常(由于该服务是非交互式的，因此我们只能访问记录的序列化异常(：

感谢您提供诊断信息！您的客户端代码不是问题所在。这可能是暂时性服务器问题。

将 Microsoft Graph .NET 客户端库的版本升级到版本 1.17.0，因为我们引入了对 504 错误进行自动重试。您应该看到此问题已通过升级得到解决。如果您不这样做，请告诉我们。
