How to redirect to https in spring boot web flux (netty server)?

[river haven]

This is from spring docs. I added this code and it does redirect to https. But when trying to log in (send a post request) from inside frontend, it can not find expected header 'csrf token' (this was working correctly before adding redirect code).

@Bean
SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
    http
        // ...
        .redirectToHttps(withDefaults());
    return http.build();
}
