24.5.1 doesn't start with a Hilla/React Parent Layout

[SebastianKuehnau]

Describe the bug

I have a Vaadin app with view implemented in Flow with a Parent Layout in React and Automatic Layouts. Starting the application I'm getting the following error message:

com.vaadin.flow.server.InvalidRouteConfigurationException: Invalid route configuration. The following Hilla route(s) conflict with configured Flow routes: 
    at com.vaadin.flow.router.internal.RouteUtil.checkForClientRouteCollisions(RouteUtil.java:653) ~[flow-server-24.5.1.jar:24.5.1]
    at com.vaadin.flow.router.internal.RouteUtil.checkForClientRouteCollisions(RouteUtil.java:613) ~[flow-server-24.5.1.jar:24.5.1]

Expected-behavior

application starts like in 24.5.0

Reproduction

go to start.vaadin.com, add flow view to your app and a main layout implemented in hilla.

try to start the app with vaadin 24.5.1

System Info

MacOS 15.0.1 Java jbr_jcef-21.0.4-osx-aarch64-b620.4 Chrome 130 IntelliJ 2024.2.4 (Ultimate Edition)

Can't reproduce. The app starts fine with @layout.tsx and

@Route("")
public class EmptyView extends VerticalLayout {

Scrap that, the project was still using 24.5.0 where it works. 24.5.1 is indeed broken

[SebastianKuehnau]

with 24.5.1 the debugger is running through RouteUtil.checkForClientRouteCollisions, which has not happened in 24.5.0.

Likely fixed by https://github.com/vaadin/flow/pull/20327
