Laravel 5 uploading zip file showing Undefined variable: e - laravel

Question

I've created a file upload method and the file uploading with the file extension like jpg, png etc are successful. However, when I upload a zip file, it says me "Undefined variable: e". To find, I did dd() at the beginning of the respective method but it still says the above error. My route is as below:
Route::post('media/savedata/{id?}/{page?}', 'Administrator\MedialibraryController#savedata');
The method is as below:
public function savedata($id, $page, Request $request) {
...
}
The content of the "network" tab is as below:
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
My intention is: If zip file is upload then it will redirect to another page however, I can't do this because even dd() is not working.
UPDATE:
Below is the Laravel Log:

My Handler.php content is below:
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);
}
}

Answer 1

Change
return $this->renderHttpException($e);
to
return $this->renderHttpException($exception);
in
app/Exceptions/Handler.php

Answer 2

You can handle the FileException exception inside your exception handler at app/Exceptions/Handler.php. Update the render method to add in the code you need. For example, if you'd like to return a validation exception, you will need to handle the validation inside the exception handler for the FileException exception.
public function render($request, Exception $exception)
{
if ($exception instanceof \Symfony\Component\HttpFoundation\File\Exception\FileException) {
// create a validator and validate to throw a new ValidationException
return Validator::make($request->all(), [
'your_file_input' => 'required|file|size:5000',
])->validate();
}
return parent::render($request, $exception);
}
This is untested, but should give you the general idea.

Answer 3

if ($exception instanceof \Illuminate\Http\Exceptions\PostTooLargeException)
return \Redirect::to('administrator/media')->with('errorMessage', 'Please upload an image.');
