我在我的網站上使用了Exm訂閱表格。當我點擊「提交」沒有發生，我在日誌中看到這個異常：Sitecore EXM 3.3訂閱表格解碼信息問題
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.
Exception: System.FormatException

這開始發生時，我升級EXM版本從3.2到3.3。在3.2版本中的所有工作得很好
我發現這是happend此異常的行：
string str3 = this._cipher.TryDecrypt(eventData.ContactId);
它看起來像使用ContactID（等於「00000000-0000-0000-0000-000000000000」）丟失
請儘量去除 \ DATA \ ViewState的文件夾下的所有文件夾，然後嘗試重現該問題再次 –
問題仍然轉載 –
我找到了發生以下異常的行： string str3 = this._cipher.TryDecrypt（eventData.ContactId）; 看起來像ContactId（等於「00000000-0000-0000-0000-000000000000」）丟失。它應該在哪裏填充？ –
