Codeception: [Yii2] Page not found in functional tests after update to 2.4.1

What are you trying to achieve?

Run this relatively simple test

        $user = $I->grabFixture('user', 'user1');
        $I->amOnPage('ru/user/login');
        $I->see('Авторизоваться', 'h2');
        $I->wantTo('ensure that login is successful');
        $I->submitForm('form#login-form', [
            'login-form[login]' => $user->username,
            'login-form[password]' => 'test',            
        ]);
        $I->seeElement('a.logout');
        $I->seeElement('.page_user_name');

What do you get instead?

Red test with error in output file <pre>Not found: Страница не найдена. </pre>. In 2.4.0 it was green. Interesting thing.

$I->amOnPage('ru/user/login');

This instruction executes successfully. But suddenly submitting on the same url says page not found. How this can be understandable?
