Pessoal, algu;ém já passou por esse problema de receber o erro:

"There is no PasswordEncoder mapped for the id "null""

Minha configuração do SpringSecurity está assim:

package med.voll.api.infra.security;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.authentication.AuthenticationManager;
import org.springframework.security.config.annotation.authentication.configuration.AuthenticationConfiguration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.http.SessionCreationPolicy;
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.web.SecurityFilterChain;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration {

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        return http.csrf(csrf -> csrf.disable())
                .sessionManagement(sm -> sm.sessionCreationPolicy(SessionCreationPolicy.STATELESS))
                .build();
    }

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

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