Why Kohana 3.3 Error reading session data on any session call after OAuth?

Question

Google

Colleagues!
I don't sleep the second night.
Connected facebook and google oath modules to Kohana.
At first everything worked and I did not notice when everything broke.
Maybe someone has come across something similar?
facebook and google in the process of authentication, create their own session.
This is where the conflict comes in.
When I first encountered this, creating my own session config helped:

<?php defined('SYSPATH') OR die('No direct script access.');

return array(
    'native' => array(
        'name' => sha1(URL::base()),
        'lifetime' => 43200,
        'encrypted' => FALSE,
    ),
    'cookie' => array(
        'name' => 'cookie_name',
        'encrypted' => TRUE,
        'lifetime' => 43200,
    ),
    'database' => array(
        'name' => 'cookie_name',
        'encrypted' => TRUE,
        'lifetime' => 43200,
        'group' => 'default',
        'table' => 'table_name',
        'columns' => array(
            'session_id'  => 'session_id',
            'last_active' => 'last_active',
            'contents'    => 'contents'
        ),
        'gc' => 500,
    ),
);

But with further development, the incident repeated itself and nothing can help.
BOM-cleaned from all files, and there are more than 600 of them.
Error message:

Session_Exception [ 1 ]: Error reading session data.

322 		{

324 			throw new Session_Exception('Error reading session data.', NULL, Session_Exception::SESSION_CORRUPT);
325 		}

79 			}
80             
81 			if(Auth::instance()->logged_in()) {
82 				Model::factory('User')->link_user_facebook_id($fb_id);
83 				$this->redirect('login/login');
84 			} else {			
85 				$user_data = Model::factory('Facebook')->parse_fb_info($fb->api('/me'));
86 				//Model::factory('User')->create_user_from_google_id($user_data);

The error occurs on line 81.
On the screen is my login controller which executes the facebook action. If the user is logged in to FB, then the return occurs here, but the function that forcibly logs in the user found in the database by Facebook_id using regular Auth tools should already work.
Tell me, what else can you try to poke with a stick?

Answer 1

The only clear explanation is here: stupid.su/kohana-3_orm_auth_session
BUT the solution didn't help.

Session conflict
When using the session Native driver and third-party libraries and modules (eg Hybridauth), conflicts may occur due to: the
inability to read/write the encrypted cookie;
use by third-party libraries session_start();
- which can lead to an error:
Session_Exception [ 1 ]: Error reading session data.
The simplest solution would be to use a database to store Kohana sessions, however, there are other solutions, such as passing the current $_session_id to session_start() or replacing it in third-party modules with Session::instance().
Important: the above error can also occur due to the banal impossibility of writing / reading session data, for example, due to unavailability / lack of write permissions in session.save_path (PHP session file storage directory, see php.ini)

Empirically found out that in principle the Auth class does not work. Somewhere I broke it.
