Laravel 5上传zip文件显示Undefined变量:e

Question

我已经创建了一个文件上传方法,并且文件扩展名jpg, png等文件上传成功.但是,当我上传一个zip文件时,它会说" Undefined variable: e".为了找到,我dd()在相应方法的开头做了但它仍然说上面的错误.我的路线如下:

Route::post('media/savedata/{id?}/{page?}', 'Administrator\MedialibraryController@savedata'); 

方法如下:

public function savedata($id, $page, Request $request) {
 ...
}

"网络"标签的内容如下:

Request URL: http://localhost/stmd/administrator/media/savedata/0/1
Request Method: POST
Status Code: 500 Internal Server Error
Remote Address: [::1]:80
Referrer Policy: no-referrer-when-downgrade

I
------WebKitFormBoundaryaHtERzAAThbQB4ae
Content-Disposition: form-data; name="fileName"; filename="gradle-3.5-bin.zip"
Content-Type: application/zip

我的意图是:如果zip文件上传,那么它将重定向到另一个页面但是,我不能这样做,因为即使dd()不工作.

更新:

以下是Laravel日志:

我的Handler.php内容如下:

public function render($request, Exception $exception)
    {
        if($this->isHttpException($exception)){
            $logFile = 'laravel.log';

            Log::useDailyFiles(storage_path().'/logs/'.$logFile);
            //echo Route::getCurrentRoute()->getAction();



            //echo $exception->getStatusCode();exit;
            switch ($exception->getStatusCode()) {

                case 404:
                    Log::info('Unable to find page.');
                    return response()->view('errors.404',[],404);

                    break;

                case 500:

                    Log::error('In Server is really going wrong.');
                    return response()->view('errors.500',[],500);

                    break;
                 default:
                    return $this->renderHttpException($e);
                break;

            }

        }
        return parent::render($request, $exception);
    }
}

改变

return $this->renderHttpException($e);

到

return $this->renderHttpException($exception);

在

app/Exceptions/Handler.php
