Laravel Backpack FIlter Not Called

I’m currently working on project using laravel backpack and try to use crud filter on the data. But the function that filtering data not being called after dropdown selected. Here is my

$this->crud->addFilter([ // select2 filter
            'name' => 'id_periode',
            'type' => 'dropdown',
            'label'=> 'Periode'
            ], function() {
                return \App\Models\Periode::all()->pluck('periode', 'id')->toArray();
            }, function($value) {
                dd($value);
                $this->crud->addClause('where', 'id_periode', $value);
        });

Is there something wrong with my code or am i missing something ?

Thx that solved the problem for me:

Solution (working for Laravel >= 5.5)

1. Configure App\Http\Middleware\TrustProxies;

protected $proxies = '**';
protected $headers = Request::HEADER_X_FORWARDED_ALL;

(For older Laravel Versions see https://github.com/fideloper/TrustedProxy)

AppServiceProvider function boot() Make sure that \URL::forceScheme('https') must NOT be set.

Thanks, @axelzuzek! Worked for me with protected $proxies = '**'; and SET(!!!) \URL::forceScheme('https') Laravel 5.6
