This browser requires transpilation to ES5.

To test your app with this browser, enable transpilation in development mode.

Transpilation can be enabled by setting the vaadin.devmode.transpile=true property for the deployment configuration using an application or a system property.

Note that transpilation is always enabled for the build-frontend Maven goal, which is also used when creating a production build of the application.
