Sitecore 7.5 logs TypeLoadExceptionHolder无法转换为Sitecore.Analytics.Model.Framework.IFacet类型

Question

我在Sitecore 7.5日志中遇到以下错误。知道我们为什么会收到这个错误吗？。

Answer 1

看来提交队列中有一些东西。

查看Sitecore“Datafolder”目录中的“Submit Queue”文件夹。 删除错误的文件并检查文件权限。

Answer 2

在我的情况下（我正在运行Sitecore 9），构面类型也发生了变化，某些旧构面对象仍在〜\ Website \ App_Data \ Submit Queue文件夹中的磁盘上进行了序列化。删除该文件夹中的文件后，问题已解决。 Sitecore之所以存储构面对象的原因是，如果由于某种原因xConnect不可用，则当前会话将被序列化（包括联系人信息和构面），并被写入〜\ Website \ App_Data \ Submit Queue文件夹。然后，Sitecore会按一定的时间间隔重试将此会话数据发送到xConnect。
