insertID()

Hello,

Getting the following exception back when using the insertID() function.

Call to undefined method CodeIgniter\Database\MySQLi\Builder::insertID()

Don't know if i'm using it the wrong way but the following line is used inside my Model.

PHP Code:

protected $table = 'Clients';

public function __construct()
{
      $this->managers = \Config\Database::connect()->table($this->table);
}
