error:object references an unsaved transient instance - save the transient instance before flushing: one.whr.simple.entity.Role

this is because when saveing new users, I didn't retrieve role from db, instead i created a new instance of role:

roleSet.add(new Role(EnumRole.ROLE_USER));

correction:

 Role userRole = roleRepository.findByName(EnumRole.ROLE_USER)
                .orElseThrow(() -> new RuntimeException("Error: Role is not found."));
        roleSet.add(userRole);
