Spring Boot 3.0.4 does not set XSRF-TOKEN into response cookie

I’m trying to set token into every response, but can’t do that. According to Spring boot documentation this should set token into cookie

public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        // ...
        .csrf(csrf -> csrf.csrfTokenRepository(CookieServerCsrfTokenRepository.withHttpOnlyFalse()))
    return http.build();

My code is and no token in response cookie:

    public SecurityWebFilterChain springSecurityFilterChain(ServerHttpSecurity http) {
        CookieServerCsrfTokenRepository repository = CookieServerCsrfTokenRepository.withHttpOnlyFalse();

            .oauth2Login(oauth2 -> oauth2
                    //....failure handler)
            .csrf((csrf) -> csrf
            .authorizeExchange(exchanges -> exchanges
                //...another pathMatchers
        return http.build();

if filter is added like so:

public class CsrfHelperFilter implements WebFilter {
    public Mono<Void> filter(ServerWebExchange exchange, WebFilterChain chain) {
        String key = CsrfToken.class.getName();
        Mono<CsrfToken> csrfToken = null != exchange.getAttribute(key) ? exchange.getAttribute(key) : Mono.empty();
        return csrfToken.doOnSuccess(token -> {
            ResponseCookie cookie = ResponseCookie.from("XSRF-TOKEN", token.getToken()).maxAge(Duration.ofHours(1))
            exchange.getResponse().getCookies().add("XSRF-TOKEN", cookie);


then token is in cookie but it’s to many characters (4936) and I get error in browser

Set-Cookie header is ignored in response from url: https://url... The combined size of the name and value must be less than or equal to 4096 characters.

If I use same filter and .csrf() with no params then token is set and GET is working, but POST is giving me 403 and ‘Invalid CSRF Token’

Hi Mosh please what is the project that is covered in the java course. Does it show how to connect java to frontend and database like MySQL?

Please anyone who has purchased the java course please help me answer the question. Does the project which is covered in the java series show how to use java as a backend and connect to a database?.
