I'm searching for a solution ... it's getting so frustrating. After a fresh installation of Lumen by Laravel, I simply can't access the "/" route. When I try to, it throws an error:
NotFoundHttpException in RoutesRequests.php line 443:
in RoutesRequests.php line 443
at Application->handleDispatcherResponse(array('0')) in RoutesRequests.php line 380
at Application->Laravel\Lumen\Concerns\{closure}() in RoutesRequests.php line 629
at Application->sendThroughPipeline(array(), object(Closure)) in RoutesRequests.php line 382
at Application->dispatch(null) in RoutesRequests.php line 327
at Application->run() in index.php line 28
Got it! ....
The solution is to change in public/index.php at line 28:
$app->run();
to
$app->run($app->make('request'));
No clue why, maybe you know.
