企业微信订阅OA审批申请状态变化回调通知（sys_approval_change）事件，RequestMessageEvent_SysApprovalChange对象上的ApprovalInfo属性为null
问题描述
当在自定义的WorkCustomMessageHandler里重写OnEvent_Sys_Approval_Change_Status_ChangeRequest(RequestMessageEvent_SysApprovalChange requestMessage)方法时，从RequestMessageEvent_SysApprovalChange上取ApprovalInfo，当审批刚刚新建时，ApprovalInfo能正常取到值，但是当审批同意或者驳回时，ApprovalInfo为null

用你测试提供的数据没问题，可是用微信实际返回的xml就有问题。
你用这个数据测一下：
<xml> <ToUserName><![CDATA[ww347c3f221bdb85ad]]></ToUserName> <FromUserName><![CDATA[sys]]></FromUserName> <CreateTime>1652167771</CreateTime> <MsgType><![CDATA[event]]></MsgType> <Event><![CDATA[sys_approval_change]]></Event> <AgentID>3010040</AgentID> <ApprovalInfo> <SpNo>202205100003</SpNo> <SpName><![CDATA[物品领用]]></SpName> <SpStatus>2</SpStatus> <TemplateId><![CDATA[3TmmDEDyvCbnHeLiszG5rBwUB9dhVNcMU3qxwH1K]]></TemplateId> <ApplyTime>1652167758</ApplyTime> <Applyer> <UserId><![CDATA[JiangYueYe]]></UserId> <Party><![CDATA[3]]></Party> </Applyer> <SpRecord> <SpStatus>2</SpStatus> <ApproverAttr>1</ApproverAttr> <Details> <Approver> <UserId><![CDATA[JiangYueYe]]></UserId> </Approver> <Speech><![CDATA[]]></Speech> <SpStatus>2</SpStatus> <SpTime>1652167770</SpTime> </Details> <Details> <Approver> <UserId><![CDATA[XuJianBing]]></UserId> </Approver> <Speech><![CDATA[]]></Speech> <SpStatus>1</SpStatus> <SpTime>0</SpTime> </Details> </SpRecord> <StatuChangeEvent>2</StatuChangeEvent> </ApprovalInfo> </xml>
会报异常
那就奇怪了，麻烦你再用这个代码测试下：
[TestMethod]
public void TestFillEntityWithXml()
{
//客服回调
var doc = XDocument.Parse(@"

RequestMessageEvent_SysApprovalChange reqPack = new RequestMessageEvent_SysApprovalChange();
reqPack.FillEntityWithXml(doc);
Assert.IsNotNull(reqPack.ApprovalInfo);
Assert.AreEqual((ulong)202205100003, reqPack.ApprovalInfo.SpNo);
}
看看测试能不能通过
我用的是vs2019 17.0.1
运行环境.net core 3.1
nuget包版本
那就奇怪了，麻烦你再用这个代码测试下：

这个是您收到的最原始的XML信息吗？
