Consider changing this

 http.apply(new JSONLoginConfigurer<HttpSecurity>()
                  .loginPage("/authenticate")
                  .successHandler(new SimpleUrlAuthenticationSuccessHandler("/dashboard"))
                  .permitAll());

to

JSONLoginConfigurer<HttpSecurity> configurer = new JSONLoginConfigurer<>();
 configurer.setBuilder(http);
 http.apply(configurer
                  .loginPage("/authenticate")
                  .successHandler(new SimpleUrlAuthenticationSuccessHandler("/dashboard"))
                  .permitAll());
