[keycloak-user] Springboot adaptor issue with browser bookmark

We have a SpringBoot application secured by Keycloak using the KeycloakWebSecurityConfigurerAdapter. When the Keycloak login page is reached the URL contains a query string with "state" and "session_state". Some of our users bookmark this login page in their browser, which stores the query string (including state & session_state). When they return to the page using the bookmark, they get an error. How can I avoid this situation? Or if there is no way, does it make sense to catch the error and redirect the user to the correct page without the problematic query string?
