How to handle undefined routes/params?

Right now i’m trying to build a basic endpoint api

  $app->group('/player', function (Group $group) {
        $group->get('', ListPlayers::class);
        $group->get('/getPlayer/{id}', GetCandidate::class);


It works if I pass an ID, but it’ll throw an exception if it’s just http://localhost/player/getPlayer/


Uncaught Slim\Exception\HttpMethodNotAllowedException: Method not allowed. Must be one of: OPTIONS in

How do I throw my own error without having slim throw the default or redirect the user to a different action?

I guess really the question would be how to handle unknown / undefined routes?

Hi! Is this Slim 3 or Slim 4?

The CORS Pre-Flight route is giving you that specific error message. There’s a bunch of things you can do.

You could remove that route if you don’t need it, Slim will then throw a not found exception instead.

You could make the argument optional:

$group->get('/getPlayer[/{id}]', GetCandidate::class);

or you could add a another route for the no argument case:

$group->get('/getPlayer', SomeClass::class);

You could add a catch all get and or post route at the end of your routes file, but this will probably lead to unintended consequences :slight_smile:

      function (Request $request, Response $response) {
          throw new HttpNotFoundException($request, 'nope');
          return $response;
