Unable to use dependency injection

[warroyo]

Hi I am attempting to use dependency inject with the services.yml file but it doesnt seem to work. here is what I have. Am i missing something?

services.yml

services:
  filesystem:
    class: Symfony\Component\Filesystem\Filesystem

  version:
    class: Skel\Lib\Version

  logstash_service:
    class: Dasher\Service\LogstashService

  project_events:
    class: Dasher\Console\Command\Gitlab\ProjectEventsCommand
    arguments: ["logstash_service"]
    tags:
            -  { name: console.command }

and the class I am attempting to use it in:

use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Input\InputOption;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Console\Input\InputArgument;
use Dasher\Service\LogstashService;
use \GuzzleHttp\Client;

class ProjectEventsCommand extends Command{
    protected $secure_config;
    protected $client;
    protected $logstash;

    public function __construct(LogstashService $logstash){

        $this->client="";
        $this->secure_config="";
        $this->logstash = $logstash;
        parent::__construct();
    }

I am getting this error:

Argument 1 passed to Dasher\Console\Command\Gitlab\ProjectEventsCommand::__construct() must be an instance of Dasher\Service\LogstashService
