Laravel Queue From API request

Hello to everyone. I have something to ask. I want to perform a function which calls the Queueable Object which stores values into my database. But my problem is that every api request I've made when I used a dispatch it returns: { }

however when every time I used dispatchNow() there's always a response like:

{ "name": "transaction_1" }

My problem is the queue is overlapping and it execute the process at the same time. Can anyone have a suggestion about my problem? Thanks. I used android as my client app.

here is my controller code below:

    $validated = $request->validate([
      'data' => 'required|array'
    ]);

    $job = new ProcessTransaction($validated);
    $data = $this->dispatchNow($job);

    return response()->json(get_object_vars($job->getResponse())['original']);

my Queueable Class looks like:

public $tries = 1;

protected $data;

public function __construct(array $data)
{
    $this->data= $data;
}

public function uniqueId()
{
    return $this->data['name'];
}

public function middleware()
{
    return [new WithoutOverlapping($this->data['name'])];
}


public function handle()
{
	$transaction = Transaction::create(['name' => $this->data['name']]);

	if (!$transaction) 
		$this->response = response(["message" => "error"], 400);
	else
		$this->response = response(['message' => 'accepted'], 200);
}

public function getResponse()
{
    return $this->response;
}
