Vaadin 23, Blank index.html page when routing any URL

I am trying to run a page using Vaadin 23, but I get index.html on any url My project uses:

• java version=17
• spring-mvc version=5.3.20
• apache tomcat version=8.5.85

But as a dependency manager on the project we use ivy and ant (this is a legacy project) I added settings for VaadinServlet in web.xml similar to the documentation (https://vaadin.com/docs/v23/configuration/properties) , and also defined VaadinApplicationConfiguration as a spring bean

 <context:annotation-config/> <bean class="com.vaadin.flow.spring.VaadinApplicationConfiguration"/> 

My project compiles successfully and I do not see any errors related to Vaadin in the logs. I added a simple test page on Vaadin

@Route("vaadin/test") public class TestView extends HorizontalLayout { private TextField name; private Button sayHello; public TestView() { name = new TextField("Your name"); sayHello = new Button("Say hello"); sayHello.addClickListener(e -> Notification.show("Hello " + name.getValue())); sayHello.addClickShortcut(Key.ENTER); setMargin(true); setVerticalComponentAlignment(Alignment.END, name, sayHello); add(name, sayHello); } } 

when I go to the URL /vaadin/test, I get an empty index.html page from the META-INF/VAADIN/webapp directory When I go to any other URL, I also get an empty index.html page

I expect that when going to the URL vaadin/test my page will open, and not an empty index.html
