【问题描述】：

当我运行我的 nestjs 应用程序时，出现此错误说

(node:71496) UnhandledPromiseRejectionWarning: Error: An invalid controller has been detected. Perhaps, one of your controllers is missing @Controller() decorator.```

和日志跟踪：

不确定是哪个控制器？如何检查？

【问题讨论】：

标签： typescript nestjs

【解决方案1】：

使用 git 找出我错误地将侦听器添加到控制器选项。我将它添加到提供程序并解决了问题。

检查屏幕截图。从模块的控制器部分中删除不需要的类。
