How to integrate Facebook login in FuelPHP website?

I am trying to integrate Facebook login with my website using FuelPHP. I am a newbie in FuelPHP. I did what is said here fuelphp-social-package

When trying to test it I am getting following error.

ErrorException [ Fatal Error ]:
Cannot use object of type Facebook as array
/home/everycite/facebook/src/base_facebook.php @ line 226

and in line 226 is follwing code of base_facebook:

public function __construct($config) {
    $this->setAppId($config['appId']);
    ...
}

$config['appId'] is showing correct api id of my app. I am not getting it. How to solve this?
