Vaadin 25: error during build (failed to resolve import @vaadin/polymer-legacy-adapter)

[javier-godoy]

Describe the bug

error during build:
[vite]: Rollup failed to resolve import "@vaadin/polymer-legacy-adapter/style-modules.js" from "J:/fc/addons/fc-addons-demos-25/src/main/frontend/generated/flow/generated-flow-imports.js".
This is most likely unintended because it can break your application at runtime.
If you do want to externalize this module explicitly add it to
build.rollupOptions.external
