    public function uploadIsNotValid();
}

Implementing in a Controller

use Unusualify\Modularous\Services\Uploader\SignUploadListener;

class FileUploadController extends Controller implements SignUploadListener
{
    public function sign(Request $request, SignS3Upload $signer)
    {
        return $signer->fromPolicy($request->input('policy'), $this);
    }

    public function uploadIsSigned($signature, $isJsonResponse = true)
    {
        if ($isJsonResponse) {
            return response()->json($signature);
        }
        return $signature;
    }

    public function uploadIsNotValid()
    {
        return response()->json(['error' => 'Invalid upload policy'], 422);
    }
}
