Are you really using 14.0.5 or 14.0.6? 14.0.6 has a serious bug which causes a lot of these kind of issues. The only workaround is to downgrade to 14.0.5

I had the same problem with a spring app. Found that removing all build artifacts and then using production mode, mvn spring-boot:run -Pproduction, resolved thie issue.

This is a follow up to the message above:

  1. Switched to Vaadin 14.4.4
  2. Rebuild entire project
  3. Deleted node_modules directory

So far, everything seems to be working.
