Class not found exception in job (queue) - laravel

Question

We want to use laravel jobs for sending out invoices to customers.
We have this job class. It expects the payment model in the constructor.
namespace App\Jobs;
use App\Jobs\Job;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
class SendInvoiceEmail extends Job implements ShouldQueue
{
use InteractsWithQueue, SerializesModels;
public $paypalModel;
/**
* Create a new job instance.
*
* #return void
*/
public function __construct($paypalModel)
{
$this->paypalModel = $paypalModel;
}
/**
* The number of times the job may be attempted.
*
* #var int
*/
public $tries = 5;
/**
* Execute the job.
*
* #return void
*/
public function handle()
{
$rechnung = new \App\Classes\Rechnung\Rechnung($this->paypalModel);
$rechnung->platzhalterErsetzen();
$rechnung->pdfErzeugen();
\App\Classes\Mail::SendPHPMail([
'email'=> $this->paypalModel->benutzer->email,
'name' => $this->paypalModel->benutzer->vorname . ' ' .$this->paypalModel->benutzer->nachname,
'type' => 'SendInvoice',
'invoicePath'=> $rechnung->pdfTargetPath
]);
$this->paypalModel->rechnungGesendet = true;
$this->paypalModel->save();
}
}
If we set the queue_driver in the env to sync it works perfectly. Now if we change the queue_driver to database and start a listener on the jobs, we always get this exception:

Why does the listener not know the class and when running in sync mode, it works as expected? Does anybody have a hint, what the reason can be and where to search for the error reason?
Thanks in advance!
UPDATE
I've added as proposed from #niraj-shah the class app\Models\Payment\PayPal\PayPal:
...
namespace App\Jobs;
use App\Jobs\Job;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use app\Models\Payment\PayPal\PayPal;
class SendInvoiceEmail extends Job implements ShouldQueue
{
...
This did not solve the problem. Still the same error message appears. Even when I delete old created jobs and did a queue:restart to load the new code. Any other hint?

Answer 1

Your code cannot find the PayPal class. Please add a use statement to the top of your code (after the other use statements)` pointing to the location of the PayPal class. E.g.
use App\Jobs\Job;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use App\Models\Payment\PayPal\PayPal;
....
