I get an error when I try to view routing in Symfony Profiler:

[1] Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "Request" from namespace "Symfony\Bundle\WebProfilerBundle\Controller". Did you forget a "use" statement for e.g. "Symfony\Component\BrowserKit\Request" or "Symfony\Component\HttpFoundation\Request"? at n/a in /Users/Julien/Sites/tfe/vendor/symfony/symfony/src/Symfony/Bundle/WebProfilerBundle/Controller/RouterController.php line 86

Using Symfony 2.8.4
