CodeEffects规则编辑器将引发异常“在保存规则的同时，未找到“ token”属性的值为“ [NULL]”的方法”

Question

我正在使用CodeEffects规则编辑器来创建具有动态操作和属性的编辑器。由于需求是动态的，因此我在其文档中使用了CodeEffects提供的FlexSource类型选项。但是，当我尝试使用相同的规则保存规则时，出现了异常。

An unhandled exception has occurred while executing the request.

我还尝试检查他们的演示项目中是否发生了相同的事情，或者工作正常。因此，当我使用.net核心应用程序时，我将其演示项目源（在此处https://codeeffects.com/Doc/Business-Rule-Demo-Project找到）转换为.net核心应用程序。除了转换外，我什么都没改变。运行项目后，我遇到了同样的异常。
