【问题描述】：
根据用户要求，我在 CRM 的报价产品实体 (quotedetail) 中添加了一个自定义字段，允许与我们的财务系统集成（目前不在此问题的范围内）。该字段名为摘要文本代码，是对纯粹为此目的而存在的自定义记录类型的查找。在我们的 CRM 开发实例中，这可以完美运行，但在 Staging/UAT 环境中，所有用户（从最受限制的系统管理员到系统管理员）在尝试使用在此字段中设置的值保存记录时都会收到以下错误：
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: An unexpected error occurred.Detail:

一点 Google-fu 暗示这是一个插件问题。但是，我们的插件有文本文件日志记录，尤其是我们为 Quote Products 提供的那个，在这种情况下甚至没有输入插件。
更奇怪的是，当这个字段的值没有设置时，错误并没有发生，所以我真的很难断言我没有错。
深入挖掘事件查看器和 WER 日志会返回以下更详细的错误，其中包含跨越 Web 服务边界的堆栈跟踪：

此时我被难住了。任何错误跟踪都没有一行通过自定义代码，更不用说终止于一个，所以这似乎是 100% CRM 因我尚无法理解的原因而出现问题。
