Google Sign-In in Vaadin 14-16

Hi!

Someone knows how to implement Google Sign In in a Vaadin 16 (or 14) Spring Boot App??

I follow the https://vaadin.com/learn/tutorials/google-login tutorial but it doesn’t works well, the first time I enter with my Google account everything works well, nut if I logout an try to login again it throws an exception “nested exception is java.lang.ClassCastException: java.lang.String cannot be cast to org.springframework.security.oauth2.core.OAuth2AuthenticatedPrincipal’”

Thanks!
