The website encountered an unexpected error. Please try again later.</br></br><em class=”placeholder”>Symfony\Component\Routing\Exception\RouteNotFoundException</em>: Route "view.products_list.page_2" does not exist. in <em class=”placeholder”>Drupal\Core\Routing\RouteProvider->getRouteByName()</em> (line <em class=”placeholder”>190</em> of <em class=”placeholder”>core\lib\Drupal\Core\Routing\RouteProvider.php</em>).
Solution:
This is the exception thrown when a route does not exist but you are using it in your twig files or somewhere else. As in the above example find “view.products_list.page_2” in your code and remove it.
<a href="{{ path('view.products_list.page_2') }}">
Then don’t forget to clear the cache.
