Spring Security BadCredentialsException

Я слежу за этот учебник по Baeldung и не вижу никаких различий (кроме, может быть, предварительно сгенерированного шаблона страницы входа в систему), но я все еще получаю BadCredentialsException при попытке войти в систему с жестко заданной комбинацией пользователь / пароль, которая, как я уже подтвердил, является в БД и пароль там зашифрован.

Вот мой код, дайте мне знать, если понадобится больше:

SecurityConfig:

@Component
@EnableWebSecurity
@SuppressWarnings("unused")
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private MyUserDetailsService userDetailsService;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/css/**").permitAll()
                .antMatchers("/error").permitAll()
                .antMatchers("/action/**").hasRole("USER")
                .antMatchers("/action_template/**").hasRole("ADMIN")
                .and()
                .formLogin()
                .loginPage("/login").failureUrl("/login-error");
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authProvider());
    }

    @Bean
    public DaoAuthenticationProvider authProvider() {
        DaoAuthenticationProvider authProvider = new DaoAuthenticationProvider();

        authProvider.setUserDetailsService(userDetailsService);
        authProvider.setPasswordEncoder(passwordEncoder());

        return authProvider;
    }

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

}

MyUserDetailsService:

@Service
@Transactional
@SuppressWarnings("unused")
public class MyUserDetailsService implements UserDetailsService {

    @Autowired
    private UserRepository userRepository;

    public UserDetails loadUserByUsername(String email) throws UsernameNotFoundException {

        User user = userRepository.findByEmail(email);

        if (user == null) {
            throw new UsernameNotFoundException(
                    "No user found with username: " + email);
        }

        final List<GrantedAuthority> authorities = new ArrayList<>();
        user.getRoles().forEach((r) -> authorities.add(new SimpleGrantedAuthority(r)));

        return  new org.springframework.security.core.userdetails.User(
                user.getEmail(),
                user.getPassword().toLowerCase(),
                true,
                true,
                true,
                true,
                authorities
        );
    }

}

Я также отредактировал свой SecurityConfig и добавил .antMatchers("/error").permitAll(), но это не помогло

Вот Репозиторий Github, он должен дать больше информации. Я понятия не имею, как это диагностировать дальше ...
