How to solve 403 forbidden when the request is legal, but the server refuses response?

I just started studying APIs with Java, Spring and Postman so I'm having some difficulties. A few days ago I made a request that returned the following error: "The request was a legal request, but the server is refusing to respond to it. Unlike a 401 Unauthorized response, authenticating will make no difference." I already tried to follow the instructions of other questions, but with no success.

I will leave the controller class to help you understand, thanks for your attention!

class controller:

import com.altercode.gaminiconblog.dto.RegisterRequest;
import com.altercode.gaminiconblog.service.AuthService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("api/auth")
public class AuthController {
@Autowired
private AuthService authService;

@RequestMapping("/signup")
public ResponseEntity signup(@RequestBody RegisterRequest registerRequest) {
    authService.signup(registerRequest);
    return new ResponseEntity(HttpStatus.OK);

}
}

You are using Spring Security, it will auto enable a CSFR protection, if you don`t expect to receive a CSFR token, just disable it.

To disable CSFR protection, create a class like this:

@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{

    @Override
    protected void configure(HttpSecurity http) throws Exception{
        http.cors().and().csrf().disable();
    }

    @Bean
    CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOrigins(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("*"));
        configuration.setAllowedHeaders(Arrays.asList("*"));
        configuration.setAllowCredentials(true);
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }

}
