Facebook php example: Fatal error

Question

I am trying to make a php facebook app. Downloaded the Facebook php sdk and used the example.php (with my own appId and secret) to try to get a example app running. I can use the example app, but when I click login with facebook and and authenticate the app it throws this exception:

"Fatal error: Uncaught GraphMethodException: Unsupported get request. thrown in /var/www/facebook_test/base_facebook.php on line 1264"

Below is the code I am using.

Any guidance would be greatly appreciated.

<?php
require 'facebook.php';
$facebook = new Facebook(array(
  'appId'  => 'myappid',
  'secret' => 'mysecretid',
  'cookie' => true,
));

// Get User ID
$user = $facebook->getUser();

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

// Login or logout url will be needed depending on current user state.
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $statusUrl = $facebook->getLoginStatusUrl();
  $loginUrl = $facebook->getLoginUrl();
}

// This call will always work since we are fetching public data.
$naitik = $facebook->api('/naitik');

?>

Edit: This is the stack trace:

#0 /var/www/facebook_test/base_facebook.php(873): 
BaseFacebook->throwAPIException(Array) #1 [internal function]: 
BaseFacebook->_graph('/naitik') #2 /var/www/facebook_test/base_facebook.php(647): 
call_user_func_array(Array, Array) #3 /var/www/facebook_test/index.php(66): 
BaseFacebook->api('/naitik') #4 {main}

The "Fatal error ..." message is what is displayed in the browser. How can I get a full stacktrace? Sorry, but this is the first time I'm developing a php web application. — Jea
It's a Fatal error because an exception is thrown that you didn't catch. Put a try-catch around the part that throws the exception. Then you can $e->getTraceAsString(); — Halcyon

// This call will always work since we are fetching public data.
$naitik = $facebook->api('/naitik');

Apparently it doesn't!
