I am facing same issue Kartik please can you help on this.

from yii2-social.

You have not mentioned where and how you received the error.

The error mentions that you failed to pass a facebook session identifier.

If you are using facebook api, check the documentation on how to use the facebook api

from yii2-social.

Sorry I know question is closed but when I use this code.
$social = Yii::$app->getModule('social');
// Render the Login button
$url = Yii::$app->request->getAbsoluteUrl(); // or any absolute url you want to redirect
helper = $social->getFbLoginHelper($url);
$loginUrl = $helper->getLoginUrl();
echo Html::a('Facebook Login', $loginUrl, ['class'=>'btn btn-primary']);

// in your other action that processes the login
// use the output from the helper
$helper = $social->getFbLoginHelper($url); // the same url
$session = $social->getFbSession(['source'=>$helper]); // do anything with this session now

// for example get the graph user object for current user
$user = $social->getFbGraphUser($session);
echo 'User is ' . $user->getName();

the error goes when I comment out the last two lines

//$user = $social->getFbGraphUser($session);
//echo 'User is ' . $user->getName();

and button appears. If these lines are removed than how a session is created. thanks in advance.

An example set of codes are provided. But you need to use them carefully. NOTE: not all code in the example is to be written altogether in the same view.

You need to read through the comments.

The button is created via Html::a

Subequently you need to write the rest of the code in the loginUrl controller action as mentioned in the comment

// in your other action that processes the login
// use the output from the helper
