C# 解决Microsoft.Crm.CrmArgumentNullException:插件和Web服务中的callManagerInfo？

我正在使用Crm dynamics 365

系统运行得很好，我没有更改任何库，但是在一些业务逻辑更改之后，我总是会出错

Microsoft.Crm.CrmArgumentNullException:callManagerInfo

在插件和web服务中，每当我尝试更新从代码到crm的任何内容时

插件错误的一个示例：

未处理的异常：System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault，Microsoft.Xrm.Sdk，Version=9.0.0.0，Culture=neutral，PublicKeyToken=31bf3856ad364e35]：OrganizationServiceFault，我们的插件引发异常：CallManagerInfo详细信息：
2b16c280-3ba9-4f53-b6b4-a3dd6f784582 -2147220891 操作状态 0 子错误码 -2146233088 OrganizationServiceFault，插件引发异常：callManagerInfo 2019-10-22T06:48:41.9265174Z 假的

我在网上搜索了很多，发现了很多类似或其他人的建议，他们建议这是因为版本更改，但实际上我没有更改版本，我尝试了修复，但对我没有帮助

---

有什么建议可以克服这个错误吗？

错误是“Value cannot null”。请查看插件错误文本的三分之二，以“OriginalException”开头的行。是的，但调试后该值不是null，我不知道这是什么意思。找出错误发生时该值为空的原因，您就可以开始解决问题了。如果我们更新某个字段值并创建新的实体，则无论我们如何更改旧实体更新，都会出现此问题。。。。。。我们非常确定不是空的，那么你必须回答这个问题“为什么我们认为它不是空的，而它却认为它是空的？”
