Как исправить баг BeanCreationException?

Добрый день! У меня есть репозиторий

public interface UserRepository extends JpaRepository<User, Long> {
    User findByUsername(String username);
}

Конфигурация приложения имеет следующий вид:

@SpringBootApplication
@EntityScan("ru.dev.avtonomki.model")
@ComponentScan("ru.dev.avtonomki")
@EnableAutoConfiguration
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

При запуске под spring boot падает со следующим сообщением:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)
