The "X" argument does not exist

I have a simple symfony console application with following entry point

#!/usr/bin/env php
<?php

include __DIR__ . '/vendor/autoload.php';

use Rkmax\Application;

$app = new Application();
$app->run();

my Application class

class Application extends BaseApplication
{
    public function __construct($name = 'myapp', $version = '0.1')
    {
        parent::__construct($name, $version);

        $this->add(new Command\SingleCommand());
    }
}

and my command

class SingleCommand extends Command
{
    const KEYWORDS = 'keywords';

    protected function configure()
    {
        $this
            ->setName("single")
            ->setDescription("Sample")
            ->addArgument(self::KEYWORDS, InputArgument::OPTIONAL, "Keywords for the search")
        ;
    }

    public function run(InputInterface $input, OutputInterface $output)
    {
        $keywords = $input->getArgument(self::KEYWORDS);
        // ...
    }
}

i cant understand where is the problem always i get the error

 [InvalidArgumentException]               
 The "keywords" argument does not exist.

You should probably override the execute method not run.

public function execute(InputInterface $input, OutputInterface $output)
{
    $keywords = $input->getArgument(self::KEYWORDS);
    // ...
}

run initializes $input and output, then validates the input and calls execute($input, $output) later.
