Error when using squire model in background job

[hsul4n]

Describe the bug
I have a model with table located in mysql database and that model belong to currency as shown below:

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Squire\Models\Currency;

class Product extends Model
{
    public function currency()
    {
        return $this->belongsTo(Currency::class);
    }
}

To reproduce
Make a job that contains a call of currency model for example.

<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Notification;

class NewProduct extends Notification implements ShouldQueue
{
    use Queueable;

    public function via($notifiable)
    {
        return ['database'];
    }

    public function toArray($notifiable)
    {
        echo $this->product->currency;
    }
}

Expected behavior
The job should executed as normal jobs
