PreAuthorize expression not finding bean reference

I’m receiving this error Caused by: org.springframework.expression.spel.SpelEvaluationException: EL1057E: No bean resolver registered in the context to resolve access to bean 'securityService' when trying to access an existing bean inside a @PreAuthorize annotation. I’ve used this pattern before on REST controllers. Using hasRole works as expected, so I think I have my security setup correctly. I’m curious if this is a known issue or limitation. I’m using Spring Boot 2.7.3 and Java 17.

UPDATE: Here is a sample project that demonstrates this https://github.com/pcalouche/grpc-starter

Thanks for hard work on this library.

// Example bean used in PreAuthorize expression
public class SecurityService {
  public boolean allow(AuthenticatedPrincipal principal) {
    // more complex stuff could be here
    return true;
  }

  public boolean block(AuthenticatedPrincipal principal) {
    // more complex stuff could be here
    return false;
  }
}

// Security configuration
@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SecurityConfig {
  @Bean // registered bean
  public SecurityService securityService() {
    return new SecurityService();
  }

    PasswordEncoder passwordEncoder = PasswordEncoderFactories.createDelegatingPasswordEncoder();
    UserDetails user =
        User.withUsername("user")
            .password(passwordEncoder.encode("password"))
            .roles("ADMIN")
            .build();
    return new InMemoryUserDetailsManager(user);
  }

  @Bean
  public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
    http.authorizeRequests().anyRequest().authenticated().and().httpBasic();
