Di container Not Available for VOLT

php7.2 been having some trouble with the dependency injector not available in phalcon 4

The app sets up no problem. I set the view using:

     $di = new FactoryDefault();

     //otherservices defined here

    $di->setShared('view', function() use($di){
        $view = new View();

       $view->registerEngines(array(".phtml" => function($view) use($di){

           $volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di);

           $volt->setOptions(array(
                "compiledPath" => "../some/cache/volt/",

           ));

           return $volt;
    }));

        $view->setViewsDir('../some/dir/');
        return $view;
    });

When this code is run, everything fires smoothly till we get to:

{{ assets.outputCss('fonts') }}

At which point the server says:

PHP Fatal error: Uncaught Error: Call to a member function outputCss() on

So i tried to see what was going on and basically:

$this->view->assets = $this->assets

Gets the assets loaded.

But then when I get down the page to:

<input type="hidden" id="signup-csrf-token" name="{{ security.getTokenKey() }}" value="{{ security.getToken() }}">

PHP Fatal error: Uncaught Error: Call to a member function getTokenKey()

security is defined in the $di as

    $di->set('security', function() use ($di){

    $security = new Security();

    //Set the password hashing factor to 12 rounds
    $security->setWorkFactor(12);

    return $security;

    }, true);

Been at this for about 3 hours now and cannot find anything in the documentation to help. if you have any ideas at all that would be great. I know phalcon 4 is not quite ready but we are migrating already because we don’t want to be rushing last minute to make all the necessary changes.
