Anylogic：无法将代理强制转换为类

如何解决Anylogic：无法将代理强制转换为类

我看了教程：https://www.youtube.com/watch?v=N2BAv6DFPhU 我的代理类型是产品。我不确定我能做些什么来解决这个错误。感谢您的帮助！

错误信息显示如下：

离散事件执行期间的异常：

com.anylogic.engine.Agent 类不能转换为tutorialkanban.Product 类（com.anylogic.engine.Agent 和tutorialkanban.Product 位于加载程序'app'的未命名模块中）

java.lang.classCastException: class com.anylogic.engine.Agent 无法转换为 class tutorialkanban.Product（com.anylogic.engine.Agent 和 tutorialkanban.Product 位于加载程序“app”的未命名模块中）
