I can't log anything from my Job's handle method, with the Log facade. Logging from controller or other part of the application with this facade works fine.
I have tried the solution here : Logging not working in laravel queue job, but it does not work with Laravel 6.17, and here : https://stackoverflow.com/a/55206727/10767428 , but it does not affect behaviour in any way.
- PHP 7.2
 - Laravel 6.17
 APP_ENV=localAPP_LOG_LEVEL=debug- Laravel runs inside Docker with Alpine image and other stuff unrelated
 
Here is my job :
class MyJob implements ShouldQueue
{
    use Dispatchable;
    use InteractsWithQueue;
    use Queueable;
    use SerializesModels;
    public function handle()
    {
       Log::warning("HI");
    }
}
The Job is correctly handled when I dispatch if, but nothing shows up in my storage/app/logs/laravel.log.
This file and the entire folder storage has 777 permissions.
I use "single" driver in config/logging.php :
        'single' => [
            'driver' => 'single',
            'path' => storage_path('logs/laravel.log'),
            'level' => 'debug',
        ],
Any ideas?

As requested, here is my config.horizon.php :

I can log from the same job when I use dipatchNow method to call it, instead of dispatch one. Any ideas why ?
