is it a bug? customResultObject()

Hello . I'm trying to get the query result using getCustomRowObject() .
Example 

PHP Code:

$query = $this->db->query("SELECT 1 as `user_id`,'[email protected]' as `email` , 'asdasd' as `password` ");

            return $query->getCustomRowObject(0,'App\Entities\User'); 


But I get an error : 

Code:

Call to undefined method CodeIgniter\\Database\\MySQLi\\Result::customResultObject()

I looked through two files:  \system\Database\BaseResult.php and \system\Database\ResultInterface.php . I did not find a method customResultObject() . Can help solve this problem?
Thanks
