DB mysql 에서는 잘 동작하던 것이 DB 변경할 일이 생겨, mysql -> postgresql 로 전환하였습니다.

데이터 insert 시 json 타입 때문에 발생한 에러인데.. 어떻게 조치하면 좋을지 모르겠습니다.

1. SchedulingTask 엔티티

@Entity
@Getter
@Setter
@NoArgsConstructor
@Slf4j
public class SchedulingTask {
    @Id
    @Column(name = "task_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
 
   @Column(columnDefinition = "jsonb")
    private String requestBodyString;
}

2. 저장 하는 코드

    public SchedulingTask save(Dbaas dbaas, int priority, ReqInfo reqInfo, String requestBodyString) {
        log.info("requestBodyString : {}", requestBodyString);
        SchedulingTask schedulingTask = reqInfo2SchedulingTaskMapper.to(reqInfo, requestBodyString, priority, dbaas);
        log.info("schedulingTask : {}", schedulingTask.getRequestBodyString());
        return schedulingTaskRepository.save(schedulingTask);
    }

3. log

repository 에 직접 저장 시, requestBodyString 을 json 으로 직접 바꿔줘야 하나요??
