[SOLVED] @PreAuthroize has role vs requestMatchers().hasRole()

I have created jwt implementation with Spring Resource Server dependency. Here is config class:

@Configuration
@RequiredArgsConstructor
@EnableWebSecurity
@EnableMethodSecurity
public class WebSecurityConfig {

    @Value("${app.chat.jwt.public.key}")
    private RSAPublicKey publicKey;

    @Value("${app.chat.jwt.private.key}")
    private RSAPrivateKey privateKey;

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http.cors().and().csrf().disable();

        http.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);

        http.exceptionHandling(
                exceptions ->
                        exceptions
                                .authenticationEntryPoint(new BearerTokenAuthenticationEntryPoint())
                                .accessDeniedHandler(new BearerTokenAccessDeniedHandler()));

        http.authorizeHttpRequests()
                .requestMatchers("/auth/sign-in").permitAll()
                .requestMatchers("/auth/sign-up").permitAll()
//                .requestMatchers("/hello").hasRole("ROLE_USER")
                .anyRequest().authenticated()
                .and()
                .httpBasic(Customizer.withDefaults())
                .oauth2ResourceServer(OAuth2ResourceServerConfigurer::jwt);

        return http.build();
    }

    @Bean
    public AuthenticationManager authManager(UserDetailsServiceImpl userDetailsService) {
        var authProvider = new DaoAuthenticationProvider();
        authProvider.setUserDetailsService(userDetailsService);
        authProvider.setPasswordEncoder(passwordEncoder());
        return new ProviderManager(authProvider);
    }

    @SneakyThrows
    @Bean
    public JwtEncoder jwtEncoder() {
        var jwk = new RSAKey.Builder(publicKey).privateKey(privateKey).build();
        var jwks = new ImmutableJWKSet<>(new JWKSet(jwk));
        return new NimbusJwtEncoder(jwks);
    }

    @SneakyThrows
    @Bean
    public JwtDecoder jwtDecoder() {
        return NimbusJwtDecoder.withPublicKey(publicKey).build();
    }

    @Bean
    public JwtAuthenticationConverter jwtAuthenticationConverter() {
        var jwtGrantedAuthoritiesConverter = new JwtGrantedAuthoritiesConverter();
        jwtGrantedAuthoritiesConverter.setAuthoritiesClaimName("scope");
        jwtGrantedAuthoritiesConverter.setAuthorityPrefix("ROLE_");

        var jwtAuthenticationConverter = new JwtAuthenticationConverter();
        jwtAuthenticationConverter.setJwtGrantedAuthoritiesConverter(jwtGrantedAuthoritiesConverter);
        return jwtAuthenticationConverter;
    }

    @Bean
    public CorsFilter corsFilter() {
        UrlBasedCorsConfigurationSource source =
                new UrlBasedCorsConfigurationSource();
        CorsConfiguration config = new CorsConfiguration();
        config.setAllowCredentials(true);
        config.addAllowedOrigin("*");
        config.addAllowedHeader("*");
        config.addAllowedMethod("*");
        source.registerCorsConfiguration("/**", config);
        return new CorsFilter(source);
    }

    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Bean
    public AuthenticationManager authenticationManager(
            AuthenticationConfiguration authenticationConfiguration) throws Exception {
        return authenticationConfiguration.getAuthenticationManager();
    }
}

And I have simple controller:

@RestController
public class HelloController {

    @PreAuthorize("hasRole('ROLE_USER')")
    @GetMapping("/hello")
    public String hello() {
        return "Hello!";
    }
}

If I use @PreAuthorize("hasRole('ROLE_USER')") I always return a 403 status code. But if I do the same but in the config file: requestMatchers("/hello").hasRole("ROLE_USER"), then it is working as expected. I have the @EnableMethodSecurity annotation so @PreAuthorize should work, but for some reason, it doesn't. Also, why do I need to add ROLE_ in hasRole() method? I thought Spring should handle it for me.

Main question is why hasRole() works for requestMatchers() but doesn't for @PreAuthorize.

Here is the link to gitHub repo if needed(don't pay attention to commit messages): https://github.com/EternalSadnes/chat-app

Update:

Here is logs after failing request to /hello endpoint with @PreAuthorize annotation:

Any ideas on how I can debug it deeper or what should I pay attention to?
