Symfony5 throws 404 in browser, but route is found in cli - php

Question

Iam using react+symfony with webpack. Everything works with simple url eg. one slash in url ("/aboutus","/moodle") but when i try access route with multiple slashes("/admin/users") i get NotFoundResource Error. But with router:matchi will find it.
Server log:
|WARN | SERVER GET (404) /admin/users
|ERROR| REQUES Uncaught PHP Exception Symfony\Component\HttpKernel\Exception\NotFoundHttpException: "No route found for "GET /admin/users"" at /home/rtkpf/Programming/Niners/vendor/symfony/http-kernel/EventListener/RouterListener.php line 136
router:match /admin/users
(master) [1]> bin/console router:match /admin/users
[OK] Route "index" matches

Component:
class DefaultController extends AbstractController
{
/**
* #Route("/{reactRouting}", name="index", defaults={"reactRouting": null}, methods="GET", requirements={"reactRouting":".+"})
*/
public function index()
{
return $this->render('default/index.html.twig');
}
}
Has someone experienced this before? Where can be a mistake?
P.S.: Ia m using symfony server

Answer 1

It says App\Controller\UserController::index() in router:match while your controller shows DefaultController, is this a possible problem?
There could also be a priority issue, since 5.1 you can use priorities in routing (https://symfony.com/blog/new-in-symfony-5-1-route-annotations-priority), perhaps try adding priority=-10, in the router annotation to prioritize it lower (0 is default) or priority=10, in case you want to increase the priority somewhere else.
