Hello everyone. There was a CSRF validation failed Everything works fine if I do not use plug-in service.php
/**
 * Dispatcher use a default namespace
 */
$di->set('dispatcher', function() use ($di) {
    $eventsManager = $di->getShared('eventsManager');
    $security = new Security($di);
    /**
     * We listen for events in the dispatcher using the Security plugin
     */
    $eventsManager->attach('dispatch', $security);
    $dispatcher = new Dispatcher();
    $dispatcher->setEventsManager($eventsManager);
    $dispatcher->setDefaultNamespace('EasyPay\Controllers');
    return $dispatcher;
});Security.php
/**
 * This action is executed before execute any action in the application
 */
public function beforeDispatch(Event $event, Dispatcher $dispatcher)
{
    $auth = $this->session->get('auth-identity');
    if (!$auth) {
        if ($dispatcher->getControllerName() != 'session') {
            $dispatcher->forward(array(
                'controller' => 'session',
                'action' => 'login'
            ));
            return false;
        }
    }
