I want to only allow the login and token api to get the token and want to require authorization for rest of the apis using JWT tokens but I am getting error while trying the login api through postman. I am getting 401 error.

WebSecurityConfig.java class

package com.springboot.quizapp.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.web.SecurityFilterChain;

import static org.springframework.security.config.Customizer.withDefaults;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig {

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http
                .authorizeHttpRequests((authz) -> authz
                        .requestMatchers("/login", "/token","/api/v1/auth/login").permitAll()
                        .anyRequest().authenticated()

                )
                .httpBasic(withDefaults());
        return http.build();
    }

}

AuthController.java

package com.springboot.quizapp.controller;

import com.springboot.quizapp.entity.User;
import com.springboot.quizapp.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/api/v1/auth")
public class AuthController {

    @Autowired
    private UserService userService;

//    private JwtService jwtService;
    @PostMapping("/login")
    public String loginUser(@RequestBody User user) throws Exception{
        return userService.authenticateUser(user);
    }

    @PostMapping("/register")
    public int registerUser(@RequestBody User user) throws Exception{
        return userService.registerUser(user);
    }
}

I am getting this error while trying to hit login api:
