SLIM ERROR TYPE: Slim\Exception\ContainerValueNotFoundException

I'm pretty new to using slim framework with twig-view. I am seeing this error when I try to render view from slim container, this is the code that returns an error page.

<?php

$app->get('/home', function($request, $response){
return $this->$view->render($response, 'home.twig');    
}); 

?>

The above code returns this errorSlim application error, but when I return a simple string like the example below:

<?php

$app->get('/home', function($request, $response){
return "Hello World!";  
}); 

?>

It outputs Hello World! correctly on the browser, but when I try this:

<?php

$app->get('/home', function($request, $response){
return $this->$view->render($response, 'home.twig');    
}); 

?>

It returns the error Slim application error. The below code is my index page.

<?php
session_start();
require __DIR__ . '/../vendor/autoload.php';

$app = new \Slim\App([
    'settings' => [
        'displayErrorDetails' => true,
    ]
]);

$container = $app->getContainer();
$container['view'] = function($container){
    $view = new \Slim\Views\Twig(__DIR__ . '/../resources/views/home.twig', [
        'cache' => false,
    ]); 

    $view->addExtension(new Slim/Views/TwigExtension(

    $container->router,
    $container->request->getUri()
));

return $view;
};



require __DIR__ . '/../app/route.php';

?>

On

What am I not doing correctly?

Make sure your .htaccess file exits in the root folder with:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^ index.php [QSA,L]
RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

You should define your views folder, not your file.

$container['view'] = function ($container) {

  $view = new \Slim\Views\Twig(__DIR__ . '/../resources/views', [
    'cache' => false
  ]);

  $view->addExtension(new \Slim\Views\TwigExtension(
    $container->router,
    $container->request->getUri()
  ));

  return $view;
}

And in your route you can do this

$app->get('/', function ($request, $response) {
  return $this->container->view->render($response, 'home.twig');
});

Notice that home.twig must be inside views folder.

The problem is that you are trying to access $this->$view but the container only knows about $this->view.
