File-routes.json (No such file or directory)

I just created a new Flow app on https://start.vaadin.com with Vaadin 24.4.0.beta2

When starting the app I get:

java.io.FileNotFoundException: /Users/simon/Workspace/frameworks/vaadin/copilot-demo/src/main/frontend/generated/file-routes.json (No such file or directory)

According to @marcoc_753 this is a known timing issue that shouldn’t prevent the app from running.
