When I going to Disable Twig template cache , Fatal error

Question

When I going to Disable Twig template cache , Fatal error . i.e

The website encountered an unexpected error. Please try again later. Error: Unsupported operand types in Drupal\Core\Template\TwigEnvironment->__construct() (line 69 of core\lib\Drupal\Core\Template\TwigEnvironment.php).

I followed below steps :

1.Copy and rename the file from sites/example.settings.local.php to sites/default/settings.local.php 2.Open settings.php file in sites/default and uncomment these lines:

if (file_exists($app_root . '/' . $site_path . '/settings.local.php')) {
include $app_root . '/' . $site_path . '/settings.local.php';
}

3.Uncomment these lines in settings.local.php

$settings['cache']['bins']['render'] = 'cache.backend.null';
$settings['cache']['bins']['dynamic_page_cache'] = 'cache.backend.null';

4. Open development.services.yml in the sites folder and add the following code

    parameters:
   twig.config:
   debug: true
   auto_reload: true
   cache: false

5. Rebuild the cache and your good to go

My development.services.yml code :

parameters: http.response.debug_cacheability_headers: true twig.config: debug: true auto_reload: true cache: false services: cache.backend.null: class: Drupal\Core\Cache\NullBackendFactory

The least hassle way is to install Drupal Console

Then run the command drupal site:mode dev (turns off caching and turns on twig debug)

Once you're done, run drupal site:mode prod (turns off twig debug, turns caching back on).
