[FIXED] TransientPropertyValueException: object references an unsaved transient instance - save the transient instance before flushing :

Issue

@Entity
@Table(name="tbl_name")
public class Test extends BaseEntity {

    @OneToOne( fetch = FetchType.LAZY)
    @JoinColumn(name = "ALL_ORG_MST_SECTION_ID",nullable = true)
    private AllOrgMst allOrgMstSection;

    @OneToOne(fetch = FetchType.LAZY )
    @JoinColumn(name = "ALL_ORG_MST_SUB_SECTION_ID",nullable = true)
    private AllOrgMst allOrgMstSubSection;


    
}

This is the model . when I insert this model one object is null value then show me the error

Post man Object pass

{
   "allOrgMstSection": {
        "id": 23
    },
    "allOrgMstSubSection": {
        "id": null
    }
}

  @Autowired
    private TestRepository testRepository;

    @Override
    public Test save2(Test entity) {
        return testRepository.save(entity);
    }

In baseEntity have the Id

Solution

{
   "allOrgMstSection": {
        "id": 23
    },
    "allOrgMstSubSection": null,
}
