Codeception AcceptanceTester::loadSessionSnapshot is undefined

Question

I am trying to test a project but unable to check the login page due to this error:

[RuntimeException] Call to undefined method AcceptanceTester::loadSessionSnapshot

This is my code:

<?php 
$I = new AcceptanceTester($scenario);
$I->wantTo('Login');
$I->amOnPage('/');
if($I->loadSessionSnapshot('loggedin')) exit();
$I->dontSee('NotFound');
//$I->dontSee('Error');
$csrf = $I->grabCookie('_token');
$I->submitForm('.form',array('login'=>array(
        'username'=>'username',
        'password'=>'*******'
    )
));
$I->saveSessionSnapshot('loggedin');
$I->see('username');

And my config is like this

# Codeception Test Suite Configuration
#
# Suite for acceptance tests.
# Perform tests in browser using the WebDriver or PhpBrowser.
# If you need both WebDriver and PHPBrowser tests - create a separate suite.

class_name: AcceptanceTester
modules:
    enabled:
        - PhpBrowser:
            url: http://myweb.com
        - \Helper\Acceptance

I generated this using the commandline command

codecept.bat generate:cept acceptance loginTest

There is no such method in PhpBrowser module, loadSessionSnapshot method is only provided by WebDriver.

Don't use exit() in tests, it kills Codeception too. Use skip method instead.

if($I->loadSessionSnapshot('loggedin')) {
    $scenario->skip('Already logged in');
}
