LinuxQuestions.org - Perl question regaurding authenticating facebook. Missing session key

A few days ago I decided to pick Perl back up and have another crack at the Facebook API. I am having trouble finding documentation that is elaborate enough for me to comprehend. Which I have come up with nothing so far. There is a great Perl module on cpan but the doc is kind of ambiguous imo. There are not many example that I can follow. Most of the code, doc, and/or examples pertain to Javascript or Java. Maybe someone here who has worked with Facebook's API or is able to figure it out, could help me out. I would greatly appreciate it!

Here is the code

Code:

#!/usr/bin/perl -w 



use strict;



use URI;

use CGI::Simple;

use Data::Dumper;

use WWW::Facebook::API;



my $app_id = 'My app id';

my $app_secret = 'My app secret';



my $query = CGI::Simple->new;



my $fb = WWW::Facebook::API->new(

        desktop                => 1,

        api_key                => $app_id,

        secret                => $app_secret,

        );



#my $query  = CGI::Simple->new;

#my $params = $query->param('auth_token');



my $access_token = $fb->auth->create_token;

#$fb->auth->get_session( $access_token );



        if ( $query->param('auth_token') ) {

        $fb->auth->get_session;( $query->param('auth_token') );

        }



my $sleep      = 15;

my $browser_cmd = 'chromium-browser';

#my $login_url  = 'https://www.facebook.com/login.php?';

my $login_url = 'https://peaceful-dawn-6605.herokuapp.com';

#my $browser_cmd = '/opt/google/chrome/chrome';



#$fb->auth->login( sleep => $sleep , browser => $browser_cmd );

system qq($browser_cmd "$login_url");



my $friends = $fb->friends->get;

print Dumper $friends;

The REST call for authentication gives no errors. It's during the get friends call where I am recieving erros. Saying i am missing a session key.

ERROR

Code:

Error during REST friends.get call:
