laravel - 添加新路由后出现Laravel错误500( undefined variable 'e')？

Question

我一直在从事我的一个旧项目，基本上我必须在其中添加一个新页面并链接到它。没什么困难，在本地一切正常。
仅在将我的修改转移到服务器后，路由拒绝工作，并在错误500中出错。
我已经打开调试并添加了一个try/catch来捕获错误，但是我无法理解可能是错误的确切来源。

Index.php:

/*
|--------------------------------------------------------------------------
| Run The Application
|--------------------------------------------------------------------------
|
| Once we have the application, we can handle the incoming request
| through the kernel, and send the associated response back to
| the client's browser allowing them to enjoy the creative
| and wonderful application we have prepared for them.
|
*/

$kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);

try {
    $response = $kernel->handle(
        $request = Illuminate\Http\Request::capture()
    );

    $response->send();
} catch(\Exception $e) {
    echo dd($e);
}

异常(exception):

      › \t);
      arguments: {▼
        $request: Request {#38 …}
      }
    }
  }
}

就像我说的那样，在本地我的路线很好。任何人都不知道会有什么问题吗？

Answer 1

我找到了问题的根源。
在我的/app/Exceptions/Handler.php中，出于某些原因，我的行崩溃了:

return parent::render($request, $e);

因为该参数实际上是$ exception。不知道怎么回事。

修复之后，我清楚地表明了为什么我新添加的路由无法正常工作:显然，我已修改的 Controller 未正确写入服务器。重新上传此文件后，一切正常。
