Twig Assetic LazyAssetManager file output problem?

Hello to everyone,

I am preparing a php library that I have developed individually. I use assig to compress twig, css and js files for the theme system in the library.

If you will be responsible for knowledgeable developers; Static file output problem does not occur when using GlobAsset or FileAsset. I get an error when I use twig with filter assetic. Two I've been working on this for days, but I have not found the solution.

I share your source code with you, I hope you can help.

Template.php

    static::$fileSystem = new Twig_Loader_Filesystem();
    static::$tpl = new Twig_Environment(static::$fileSystem, $configArr);

    $am = new AssetManager();
    $fm = new FilterManager();
    $fm->set('cssrewrite', new CssRewriteFilter());

    static::$factory = new AssetFactory('C:/WinNMP/WWW/bulk/css/');
    static::$factory->setAssetManager($am);
    static::$factory->setFilterManager($fm);
    static::$factory->setDebug(true);
    static::$factory->addWorker(new AssetVersionWorker('1.0.0'));
    //static::$factory->addWorker(new CacheBustingWorker());

    $am = new LazyAssetManager(static::$factory);

    // enable loading assets from twig templates, caching the formulae
    $am->setLoader('twig', new TwigCachingFormulaLoader(static::$tpl));
    $templates = array($dir.self::HtmlDir.'/content.twig');
    // loop through all your templates
    foreach ($templates as $template) {
        $resource = new TwigResource(static::$fileSystem, $template);
        $am->addResource($resource, 'twig');
    }

    $writer = new PersistentAssetWriter(Config::get('cache.assets.frontend'));
    $writer->writeManagerAssets($am);

    static::$tpl->addExtension(new AsseticExtension(static::$factory));

    {% endblock %}

This is the error:
