Laravel 7.28.3: Supervisor Throwing Error on Execution of New Job **PHP Fatal error: method_exists()**

Question

I have created a new job in laravel 7.28.3 and dispatch it from controller. I am using Database as Queue Connection and its dispatching absolutely fine (Confirmed by checking in the database jobs table).

Job creation command:

php artisan make:job NewJob

When Supervisor tries to run the job it throws following error.

PHP Fatal error: method_exists(): The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "App\Jobs\NewJob" of the object you are trying to operate on was loaded before unserialize() gets called or provide an autoloader to load the class definition

If i initiate the queue:work manually it works fine and show me results of job using following command:

{PROJECT_PATH}/artisan queue:work --tries=3 --timeout=0 --queue=default

Steps Done So far:

• Reloaded Supervisorctl
• Restarted Supervisor Service
• Executed composer dump-autoload

Note: Old Job working absolutely fine.

namespace App\Jobs;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;

class NewJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct()
    {
        
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        $message = "Test";
        echo $message;
        dd($message);
    }
}

Dispatched from Controller

dispatch(new NewJob());
