Laravel 5.7 作业队列未异步运行

I'm trying to use Laravel 5.7 jobs queue to make some insertions/updates in my database and i problably made something wrong because when the job is called its seems to be blocking my application, therefore, not running asynchronously. My code is in the following structure:

.env

BROADCAST_DRIVER=log
CACHE_DRIVER=file
QUEUE_CONNECTION=sync
SESSION_DRIVER=file
SESSION_LIFETIME=120

queue.php

'default' => env('QUEUE_CONNECTION', 'sync'),

'connections' => [

    'sync' => [
        'driver' => 'sync',
    ],

    'database' => [
        'driver' => 'database',
        'table' => 'jobs',
        'queue' => 'default',
        'retry_after' => 90,
    ],

job_caller.php

method_name(){ 
  InsereProspeccao::dispatch($path, $evento, $equipe)->onQueue('jobs');
  retur some_msg_to_user;
}

job_name.php

use IlluminateBusQueueable;
use IlluminateQueueSerializesModels;
use IlluminateQueueInteractsWithQueue;
use IlluminateContractsQueueShouldQueue;
use IlluminateFoundationBusDispatchable;

class InsereProspeccao implements ShouldQueue{

use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

  private $path = '';
  private $evento = '';
  private $equipe = '';


 public function __construct($path, $evento, $equipe){
     $this->path = $path;
     $this->evento = $evento;
     $this->equipe = $equipe;        
 }

   public function handle(){
      //all program logic
      //access DB for insert/update
   }

}

Obs.:我正在阅读文档，但我找不到问题所在！
