Angular NG Build中的脚本优化--prod在Firebase部署/服务期间导致一个空白屏幕

我一直在努力让我的Angular9应用程序使用Firebase正确部署。在ng build中使用--prod标记时，firebase部署/服务命令会导致一个空白屏幕。在Chrome上检查开发工具的网络选项卡时，文件在dist/projectname文件夹中被正确检索。仅当我在运行“ng build”时未使用--prod标记时，应用程序才成功加载。在修改Angular.json文件中的一些值后，我注意到在--prod构建期间禁用脚本优化会导致在firebase部署/服务期间成功加载。我的问题是，在脚本优化过程中发生了什么可能会导致此问题

这是我的Angular.json文件：
