.net - OperationVetoedException - 更新现有(唯一)文档时

Question

当我尝试更新我的 RavenDB 数据库中的文档时，我收到了 OperationVetoedException。

我的 RavenDB 和 UniqueConstraintsBundle 版本是 960(而且一直是，从未从任何以前的版本更新)。

我已经检查过，但在数据库中找不到任何重复项。所以我不明白为什么会出现这个错误。

下面我的代码示例中的列表 oldVisitorSessions 仅包含唯一对象。

代码

using (var session = _documentStore.OpenSession())
{
    foreach (var visitorSession in oldVisitorSessions)
    {
        visitorSession.ProspectType = string.Empty;
        session.Store(visitorSession);
    }

    session.SaveChanges();
}

异常

请注意，您在“session_id”上有一个唯一约束失败，很可能您将它设置为 null，对吗？还有一个东西也是空的。
