操作VetoedException - 更新现有(唯一)文档时

Question

当我尝试更新RavenDB数据库中的文档时，我收到一个OperationVetoedException。

我的RavenDB和UniqueConstraintBundle版本是960（并且一直都是，从未从以前的版本更新过）。

我已经检查过，在数据库中找不到任何重复项。所以我不明白这个错误怎么可能。

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

法典

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

例外

请注意

，您在"session_id"上有一个唯一的约束失败，很可能您将其设置为 null，对吗？还有一件事也是空的。
