Laravel 5.3 class not found - php

Question

I just upgraded from laravel 5.2 to laravel 5.3
Currently I have troubles with the Mailables.
I always receive the ReflectionException Class not found. The strange thing is that, when I try sending the mail directly (without queuing), no problems occur.
I reviewed the jobs table in my database, as I am using the database queuing driver. But that doesn't seems to be the issue.
Here is the full stacktrace:

My mailable class:
<?php
namespace App\Mail;
use Illuminate\Bus\Queueable;
use Illuminate\Mail\Mailable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Contracts\Queue\ShouldQueue;
use App\Event;
use App\Visitor;
use App\Organisation;
class OrderReceived extends Mailable
{
use Queueable, SerializesModels;
private $visitor;
private $event;
private $organisation;
private $bankingCode;
/**
* Create a new message instance.
* #param App\Visitor $visitor The visitor who bought the tickets
* #param App\Event $event The event where the visitor bought tickets from
* #param App\Organisation $organisation The organisation that hosts the event
* #param string $bankingCode The formatted banking code the user should use for payement
* #return void
*/
public function __construct(Visitor $visitor, Event $event, Organisation $organisation, $bankingCode)
{
$this->visitor = $visitor;
$this->event = $event;
$this->organisation = $organisation;
$this->bankingCode;
}
/**
* Build the message.
*
* #return $this
*/
public function build()
{
return $this->view('emails.visitor.payementRequestEmail')
->subject(trans('messages.emailPayementRequest'))
->with([
'langCode' => \App::getLocale(),
'eventName' => $this->event->name,
'organisationName' => $this->organisation->name,
'name' => $this->visitor->firstName.' '.$this->visitor->lastName,
'bankAccount' => chunk_split($this->organisation->bankAccount,4,' '),//format to ISO 13616
'bankingCode' => $this->bankingCode,
'url' => $this->organisation->url,
'color' => $this->organisation->colorAsHex,
'ticketAmount' => $this->visitor->seats()->count(),
'totalPrice' => $this->visitor->calculateTotalPrice(),
'email' => $this->organisation->email,
'userEmail' => $this->visitor->email,
'printedByOrganisation' => $this->visitor->printTicketsByOrganisation,
]);
}
}
And finally, the call to send the e-mail:
Mail::to($visitor->email)->queue(new OrderReceived($visitor, $event, $event->organisation()->first(), $humanBankingCode));
What am I doing wrong? Or is this a bug in Laravel?

Answer 1

After configuring the mail settings in config/mail.php, use the Mail class in your controller and place the below code
use Illuminate\Support\Facades\Mail;
or
use Mail;
Then execute the code. Its working fine for me.
