Using the base example for laravel I get following exception:

ErrorException (E_NOTICE) Undefined index: native_type

/vendor/koolreport/core/src/datasources/PdoDataSource.php:

$cType = $this->guessType($info["native_type"]);

The issue seems to be caused by columns of type "blob".

The laravel db connection it configured as type "mysql" but looks like koolreport is treating it as a Pdo connection?

following the example I use this code:

    function setup()
    {
        // Let say, you have "sale_database" is defined in Laravel's database settings.
        // Now you can use that database without any futher setitngs.
        $this->src("mysql")
        ->query("SELECT * FROM sale_database")
        ->pipe($this->dataStore("offices"));
    }

in laravel database.php the connection has the mysql driver configured

        'mysql' => [
            'driver' => 'mysql',
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),

yes, notice is gone
