Hi team, I have created one codeIgniter project. Here,i used use \koolreport\codeigniter\Friendship; method to connect database.

But, i have got error when getting data from database like,

 Uncaught Error: Call to undefined method CI_DB_mysqli_result::unbuffered_row() in C:\xampp\htdocs\myproj\application\libraries\koolreport\packages\codeigniter\CIDataSource.php:105

My source file is

<?php

require APPPATH."/libraries/koolreport/autoload.php";

class MyReport extends \koolreport\KoolReport
{
   use \koolreport\codeigniter\Friendship;
    use \koolreport\clients\Bootstrap;

    function settings()
    {
      return array(
            "assets"=>array(
                "path"=>"../../assets",
                "url"=>"assets",
            ),
           // "dataSources"=>array(
           //      "alljobs"=>array(
           //          "connectionString"=>"mysql:host=localhost;dbname=dbname",
           //          "username"=>"root",
           //          "password"=>"",
           //          "charset"=>"utf8"
           //      ),
           //  )
        );
        
    }
   protected function setup()
    {
        $this->src("default")
        ->query("select * from nrm_business")
        ->pipe($this->dataStore("jobs_list"));
    }
}

Need some solution. Appreciated.
