how to disable laravel 5.4 default error handler

Question

I am currently working on a laravel project. I need to redirect all error pages to 404 page not found page.

public function render($request, Exception $exception)
        {
            if ($this->isHttpException($exception)) {
                switch ($exception->getStatusCode()) {

                        // not authorized
                        case '403':
                                return \Response::view('404',array(),403);
                                break;

                        // not found
                        case '404':
                                return \Response::view('404',array(),404);
                                break;

                        // internal error
                        case '500':
                                return \Response::view('404',array(),500);
                                break;

                        default:
                                return $this->renderHttpException($exception);
                                break;
                }
        } else {
                return parent::render($request, $exception);
        }



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

Is there anyway to redirect error page to 404 page?. Also the validation errors are not displaying in this code(Redirecting to 404 when validation errors occurs). I am using the version 5.4.

Answer 1

Its Bug of Laravel 5.4 modified on laravel 5.5

https://github.com/laravel/framework/pull/18481

change file vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.php

if (! $this->isHttpException($e) && config('app.debug')) {
        return $this->toIlluminateResponse($this->convertExceptionToResponse($e), $e);
    }
    if (! $this->isHttpException($e)) {
       return \Response::view('404',array(),500);
    }
    return $this->toIlluminateResponse($this->renderHttpException($e), $e);

How about:

if ($this->isHttpException($exception)) {
    abort(404);
}
