我在将我在Next 12中编写的旧项目迁移到Next 13时遇到错误。
Console Error Log
我在我的代码中找不到错误。我在谷歌上搜索了一下，但我找不到任何解决方案。它没有解释我的代码中的任何错误。我该如何解决它呢？
我不能尝试任何东西，因为它没有解释我的代码的任何错误。请让我知道什么是错误的根源。谢谢。
++++++++++导航. js

function useRouter() {
    const router = (0, _react).useContext(_appRouterContext.AppRouterContext);
    if (router === null) {
        throw new Error('invariant expected app router to be mounted');
    }
    return router;
}

我认为“next/navigation”包含此文件（navigation.js）
当路由器为空时抛出此错误，但我仍然不知道为什么路由器为空。
