Running Spatie's MediaLibrary conversions with Supervisor

Hi all

I have a multi-tenant application where I use supervisor to run some queue workers and also use Spatie's media library extension. I have the MedLibrary extension conifgured to save conversions of files to my public filesystem when a user uploads a file like this:

public function registerMediaConversions(Media $media = null)
    {
        $this->addMediaConversion('avatar')
            ->width(256)
            ->height(256)
            ->format('png')
            ->performOnCollections('avatars');

        $this->addMediaConversion('thumb')
            ->width(64)
            ->height(64)
            ->format('png')
            ->performOnCollections('avatars');

        $this->addMediaConversion('cover')
            ->width(1500)
            ->format('png')
            ->performOnCollections('covers');
    }

This worked fine when I was running it with *php artisan queue:work", but I'm getting failed jobs when running this with supervisor with the following error:

League\Flysystem\FileNotFoundException: File not found at path: 12/20210225_10_53_30pm.jpg in /var/www/my-app/vendor/league/flysystem/src/Filesystem.php:389

From what I can see, supervisor might be looking in the wrong place for these files to convert? How can I correct this?
