Can any genius one explain why stats.json is not created?
I use Vaadin 14.2 with pnpm enabled along with JSF and Wildfly 18. try to display embedded vaadin component on JSF page according WebComponentExporter.
No error during compilation and build, the application starts and runs good, only when I navigate to that specific page which has embedded component the following error happens and on the page only embedded doesn’t show up.
=================== Vaadin DeploymentConfiguration ====================
Vaadin is running in production mode.
