RavenDB C#客户端将错误抛出为无效节点标记字符:n

Question

我正试图删除RavenDB中的一个文档，该文档有3个节点在一台机器中运行(开发设置(。以下是删除文档的代码。

public bool Remove<T>(string id) where T : new()
{
bool bResult = false;
using (var session = _session.OpenSession())
{
session.Delete(id);
session.SaveChanges();
bResult = true;
}
return bResult;
}

但它在线路session.SaveChanges();上抛出错误

无效的节点标记字符：n。。。

堆栈跟踪：

Answer 1

我昨天遇到了同样的错误。我在另一台机器上恢复了数据库，在那里我安装了全新的RavenDB，并(懒惰(命名了新的实例节点"A"。当更改向量和实例标记名称不匹配时，RavenDB当前似乎无法删除文档。

节点标签不匹配

这看起来像是代码中的一个诚实错误，而不是故意的行为。。但这只是我的猜测，因为我在4.1文档中没有发现任何关于这种行为的信息。

解决方案(如果确认不匹配(：

您可以尝试在集群中添加一个新节点，该节点具有与锁定文档的名称匹配的更改向量。

在我的情况下，我无法将独立的RavenDB配置为节点标签超过4个字符(这在Docker上没有问题(。。。那个么可能更难使数据库达到一致状态

或者尝试导出和导入数据。它修复了这个问题，因为更改向量会更新并匹配新的节点标记。
