Shared microservice, Micronaut error - Multiple possible bean candidates found - dependency-injection

Question

I am trying to build a simple API using Micronaut to fetch all users, which works properly on localhost, but facing the below issue with docker image -
Internal Server Error: Error instantiating bean of type [com.cawstudios.authentication_service.controllers.UserController]\n\nMessage: Multiple possible bean candidates found: [io.micronaut.aop.InterceptorRegistry, io.micronaut.aop.InterceptorRegistry]\nPath Taken: new UserController(UserRepository userRepository) --> new UserController([UserRepository userRepository]
Structure -
Authentication-service
- Controllers
- UserController
- Reposotories
- UserRepository
Common
- Entities
UserEntity
I have a requirement to use 1 DB across multiple microservices.
Common is a shared service where I am trying to put all the entities so that any microservice can use them by adding common as their dependency.
UserController
import com.cawstudios.authentication_service.repositories.UserRepository;
import com.cawstudios.common.entities.UserEntity;
import io.micronaut.http.HttpResponse;
import io.micronaut.http.MediaType;
import io.micronaut.http.annotation.Controller;
import io.micronaut.http.annotation.Get;
import java.util.List;
#Controller("/users")
public class UserController {
private final UserRepository userRepository;
public UserController(final UserRepository userRepository) {
this.userRepository = userRepository;
}
#Get("/")
public HttpResponse<List<UserEntity>> getUsers() {
List<UserEntity> userModels = this.userRepository.findAll();
return HttpResponse.ok(userModels);
}
UserRepository
import com.cawstudios.common.entities.UserEntity;
import io.micronaut.data.annotation.Repository;
import io.micronaut.data.repository.CrudRepository;
import java.util.List;
import java.util.UUID;
#Repository
public interface UserRepository extends CrudRepository<UserEntity, UUID> {
#Override
List<UserEntity> findAll();
}

You cannot have a dependency on a shaded/shadowed jar
