Q: 

How to autowire an argument in the constructor of the ImageUploader service? The $fileUploader argument should be autowired to a non-autowirable service with ID aws.s3_file_uploader.

a) 
namespace App\Service;

use Aws\Service\S3FileUploader;
use Symfony\Component\DependencyInjection\Attribute\Autowire;

class ImageUploader
{
    public function __construct(
        #[Autowire('aws.s3_file_uploader')]
        private readonly S3FileUploader $fileUploader,
    ) {
    }
}
b)

Both C and D are valid.

c) 
namespace App\Service;

use Aws\Service\S3FileUploader;
use Symfony\Component\DependencyInjection\Attribute\Autowire;

class ImageUploader
{
    public function __construct(
        #[Autowire('@aws.s3_file_uploader')]
        private readonly S3FileUploader $fileUploader,
    ) {
    }
}
d) 
namespace App\Service;

use Aws\Service\S3FileUploader;
use Symfony\Component\DependencyInjection\Attribute\Autowire;

class ImageUploader
{
    public function __construct(
        #[Autowire(service: 'aws.s3_file_uploader')]
        private readonly S3FileUploader $fileUploader,
    ) {
    }
}
