With spring boot vaadin spring.jpa.open-in-view not working

I have a Spring Boot based app with vaadin frontend, but the spring.jpa.open-in-view function is not working. The spring boot version is 2.1.2.RELEASE. As I see the OpenEntityManagerInViewInterceptor is registered correctly, but it is called once, when the application loaded. When any backend call invoked it is not triggered.
