Sitecore EXM 3.3订阅表单解码消息问题

我在我的网站上使用Exm订阅表单。当我单击“提交”时，什么也没有发生，我在日志中看到此异常：

11:47:00 ERROR unhandled exception thrown while processing task '0x479FA17B72734C448A640E959089B01F' from task pool 'sent_message_task_pool'. The task has not reached the maximum number of Attempts to process a failing task and is postponed.

这是在我将EXM版本从3.2升级到3.3时开始发生的。在3.2版本中，所有操作都很好

我发现一行出现此异常：

string str3 = this._cipher.TryDecrypt(eventData.ContactId);

---

看起来ContactId（等于“00000000-0000-0000-0000-0000-000000000000”）丢失了

您的Sitecore版本是什么？是8.1更新3吗？如果没有，您是否也更新了Sitecore版本？因为EXM 3.3需要Sitecore 8.1更新3

请尝试删除\Data\viewstate文件夹下的所有文件夹，并尝试重新生成此问题。问题仍然存在。我发现发生此异常的行：string str3=this.\u cipher.TryDecrypt（eventData.ContactId）；看起来ContactId（等于“00000000-0000-0000-0000-0000-000000000000”）丢失了。应该在哪里填写？您是否添加了所需的连接字符串，即EXM.CryptographicKey和EXM.AuthenticationKey？c、 f.关于“是”的安装指南，我已添加此值请尝试删除\Data\viewstate文件夹下的所有文件夹，并尝试再次复制此问题。问题仍在复制。我发现一行出现此异常：string str3=this.\u cipher.TryDecrypt（eventData.ContactId）；看起来ContactId（等于“00000000-0000-0000-0000-0000-000000000000”）丢失了。应该在哪里填写？您是否添加了所需的连接字符串，即EXM.CryptographicKey和EXM.AuthenticationKey？c、 f.是的，我已经添加了此值Sitecore 8.1版更新3-Sitecore.NET 8.1（版本160519）Sitecore 8.1版更新3-Sitecore.NET 8.1（版本160519）
