Vaadin 25: Lumo.css not found

Flow
1

Vaadin 25.0.2
Spring Boot 4.0.1

/ui/lumo/lumo.css returns HTTP 404 (Not Found).
Vaadin is running under the context path /ui/.
In application.yml a vaadin.urlMapping is configured so requests are routed to “/ui/*”.
PWA start path is set with @PWA(startPath = “/ui”).

@StyleSheet(Lumo.STYLESHEET) is also set.

Is there a problem wit another context path?

You defined a servlet mapping, not a context path. You need to use the context:// pseudo protocol with the stylesheet annotation in this case
