Problem with Starter for Vaadin Flow version11 on localhost with ie11

Hello, if I run Starter for Vaadin Flow on my jetty:run environment,
it doesn’t work on IE11 http://localhost:8080, on chrome and firefox I don’t have a pb.
Is there anything else to configure?
Thank you.

IE11 is only supported with transpilation, which happens when you are building a production bundle. Read more here:
