Lavavel 5: Error page middlewares are not accessible - laravel

Question

I'm using Laravel 5.0 and getting one issue. My site is working fine when there is no error like 404, 500 etc. But when there is error on my site then it render error page but some middlewares are not loading.
My site has two parts frontend and backend. Both parts have diff-diff middlewares which I'm using. I'm using some number of custom middlewares, some of them I'm using on frontend and some of them using on backend. But when there is any error on site then middlewares are not working which are loaded in $routeMiddleware array in Kernel.php file.
I research number of articles but all gives me same solution to load all required middlewares in $middleware, which seems not fine to me. Because in $middleware array all middlewares are loading for both fronend and backend sections. But I need to load spacial middlewares only single section. How could I implement this.
This is my kernel.php file
class Kernel extends HttpKernel {
/**
* The application's global HTTP middleware stack.
*
* #var array
*/
protected $middleware = [
'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
'Illuminate\Cookie\Middleware\EncryptCookies',
'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
'Illuminate\Session\Middleware\StartSession',
'Illuminate\View\Middleware\ShareErrorsFromSession',
// 'App\Http\Middleware\VerifyCsrfToken',
];
/**
* The application's route middleware.
*
* #var array
*/
protected $routeMiddleware = [
'auth' => 'App\Http\Middleware\Authenticate',
'auth.frontend' => 'App\Http\Middleware\FrontendAuthenticate',
'auth.basic' => 'Illuminate\Auth\Middleware\AuthenticateWithBasicAuth',
];
}
And this is my route.php file code
Route::group(['middleware' => 'auth.frontend'], function() {
Route::get('/home', ['as' => 'home', 'uses' => 'HomeController#index']);
Route::get('/inner_page', ['as' => 'inner_page', 'uses' => 'HomeController#inner_page']);
});
How this is possible, please help me on this issue.

As explained in documentation, you must define a terminate($request, $response) method to run the middle-ware after the response is ready to be sent to the browser. The terminate($request, $response) method should receive both the request and the response.
then you can either add your middle-ware to the global or route middle-ware arrays.
example :
<?php
namespace App\Http\Middleware;
use Closure;
class FrontendAuthenticate
{
public function handle($request, Closure $next)
{
return $next($request);
}
public function terminate($request, $response)
{
// Check if the $response is an error and then do stuff
}
}
