Invalid CSRF Token found for request

Question

My Security Configuration in Spring:

@Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                    .cors()
                .and()
                    .authorizeRequests()
                    .antMatchers("/user/save")
                    .permitAll()
                .and()
                    .authorizeRequests()
                    .antMatchers("/user/**")
                    .hasRole("USER")
                .and()
                    .httpBasic()
                .and()
                    .logout()
                    .clearAuthentication(true)
                    .invalidateHttpSession(true)
                    .deleteCookies("JSESSIONID")
                    .deleteCookies("XSRF-TOKEN")
                    .permitAll()
                .and()
                    .csrf().csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse());
    }

I am using Angular 6 on the front-end. I am doing a POST on the endpoint /logout. I can see the JSESSIONID and the XSRF cookies being sent on the request (using the developer tools in Chrome).

However, on the console of the Spring Server Side Application I get the following stack-trace:

Invalid CSRF token found for http://localhost:8009/logout

...and the logout request fails.

I cannot understand why the XSRF token is not being updated (if that is so), or why the token is invalid. Any help is appreciated.
