webcomponentsjs | polyfills supporting the HTML Web Components specs | User Interface library

So I have an application which uses vaadin (14) and the keycloak spring boot adapter (11). I looked at keycloaks authorization example for spring boot called "app-authz-springboot" available here: https://github.com/keycloak/keycloak-quickstarts/tree/latest/app-authz-springboot When i execute the example everything works fine but when i wire up my vaadin application to the keycloak instance from the example and copy the application.properties file from the spring half of the same example it fails to set up the policy enforcement configuration. it gives me the error message:
