     * @param array  $res
     * @return string|null
     */
    public function sellVoucher(
        array $res
    ): ?string {
        
        if ($res && isset($res['certNumber']))  {
            return (string)$res['certNumber'];
        }

        return null;
    }

and get
WARNING @return string|null does not match method signature (Array).
