Spring exception raise message - No message available

I need to reveal the messages of some exceptions in my spring server

When i throwing an exception inside the server i got the 500 status error message with the message - "No message available"

I used WebSecurityConfigurerAdapter to override some security stages

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{
   @Override
   protected void configure(HttpSecurity http) throws Exception{
      http.httpBasic().disable();
      http.cors().and().csrf().disable().authorizeRequests(); }

I Know that i can add the exception handling to the HttpSecurity but i dont know how to make it reveal the exception message to the client
