Hi @kaxias

What version of Twig-View are you using? Because the trace-entries 14 and 15 tell

#14 D:\laragon\www\container\vendor\slim\twig-view\src\Twig.php(124): Twig\Environment->render('auth/login.twig', Array)
#15 D:\laragon\www\container\vendor\slim\twig-view\src\Twig.php(180): Slim\Views\Twig->fetch('auth/login.twig', Array)

So the method Twig->fetch() gets called (entry 15) and in line 124 (entry 14) which is therefore part of that method, Environment->render() gets called. But looking at the source of the current 3.x branch, the method Twig->fetch() is defined on lines 142-147. https://github.com/slimphp/Twig-View/blob/3955c519658730cc45865b71e0ad876c6d1758f2/src/Twig.php#L142-L147

Maybe you should update your Twig-View installation.

I’m using slim-twig 3.0.0-beta and l did try 3.x-dev same error.

[adriansuter]

I guess the Twig instance gets overriden somewhere in the code. If you refer to your repo slim-skleton, then I just quickly checked and found, that the registered function for the view key in \App\Providers\TwigServiceProvider::register gets called two times. Therefore you would get a new instance for every call.

I changed the code to the following

    /**
     * @return void
     * @throws \Twig\Error\LoaderError
     */
    public function register(): void
    {
        $twig = Twig::create(Config::get('twig.path'), (array)Config::get('twig.settings'));
        foreach ((array)Config::get('twig.functions') as $function) {
            $twig->getEnvironment()->addFunction($function);
        }

        $this->getContainer()->add('view', $twig);
    }

and it found the special Slim Twig functions.

But I am not sure if this is the way to go - never used the league container.

thank you @adriansuter to mention twig isn't singleton, I did make singleton add true in the third parameter on the method add.

$this->add(parameter, parameter, true);

now work fine, thanks for the help.

Hello, @kaxias Could you explain to me how you solved it, I have the same problem. Where are you added that line of code? $this->add(parameter, parameter, true);

my composer.json

"slim/psr7": "^1.1",
"slim/slim": "^4.5",
"slim/twig-view": "^3.1"

my repositories.php:

       Twig::class => function (ContainerInterface $container) {
            $twigSettings = $container->get('settings')['twig'];
            $options = $twigSettings['options'];
            $options['cache'] = $options['cache_enabled'] ? $options['cache_path'] : false;
            $twig = Twig::create($twigSettings['paths'], $options);
            // Add extension here
            $twig->addExtension(new DebugExtension());
            $twig->getEnvironment()->addGlobal('session', $_SESSION);
            return $twig;
        },
        TwigMiddleware::class => function (ContainerInterface $container) {
            return TwigMiddleware::createFromContainer($container->get(App::class), Twig::class);
        },
