Vaadin 10+: How do I handle uncaught exceptions?
In Vaadin 8:
UI.getCurrent().setErrorHandler(e -> handleError(e));
setErrorHandler does not exist in Vaadin 11, and I cannot find a corresponding method or documentation.

In Flow (Vaadin 10+) there is a mechanism that catches uncaught exceptions in Router. So you can create error views, which are shown when defined exception is captured. They are created by implementing HasErrorParameter interface typed with the exception. Below is an example from Vaadin documentation:
@Tag(Tag.DIV)
public class RouteNotFoundError extends Component
implements HasErrorParameter<NotFoundException> {
@Override
public int setErrorParameter(BeforeEnterEvent event,
ErrorParameter<NotFoundException> parameter) {
getElement().setText("Could not navigate to '"
+ event.getLocation().getPath() + "'");
return HttpServletResponse.SC_NOT_FOUND;
}
}
I recommend to read more from the documentation.
