Nest JS无法读取未定义的属性

Question

我的应用程序工作正常，在尝试使用 swagger 获取文档后它停止了，我认为这可能是一个依赖问题，但在任何地方都找不到它。

我不断收到错误消息

错误无法读取未定义的属性“getSymbol”

我不知道 getSymbol 是在哪里使用的，并且该错误似乎没有多大帮助。希望有人可以帮助我解决这个问题。完整的应用程序代码可以在以下位置找到：

欢迎任何帮助。

编辑：在开发模式下运行我得到以下输出：

Answer 1

应用程序中存在与路由相关的问题。我在控制器内有一个解析器，用于在具有第一个参数的路线“aluno”之间引导正确的路线。一旦我选择了没有参数的路线并将其首先放在控制器上，就不再需要解析器了，问题就消失了。希望这个答案可以帮助更多遇到同样问题的人。
