[Bug] failed to initSort as fieldRelations is empty

[Nicole1983]

What happened

a.i.m.w.e.LogableEventListener:88 - execute listener WorkflowEventLogEntity(id=null, processId=20, processName=CREATE_GROUP_RESOURCE, processDisplayName=Create Group, inlongGroupId=sync004, taskId=45, elementName=InitSort, elementDisplayName=Group-InitSort, eventType=TaskEvent, event=COMPLETE, listener=SortConfigListener, startTime=Tue Feb 06 13:31:35 CST 2024, endTime=null, status=-1, async=0, ip=172.25.0.8, remark=null, exception=failed to build sort config for groupId=sync004, fieldRelations is empty) error:
org.apache.inlong.manager.common.exceptions.WorkflowListenerException: failed to build sort config for groupId=sync004, fieldRelations is empty

配置数据同步，运行之后，得到以上错误log
看了issue https://github.com/apache/inlong/issues/5157，这个是不是个bug呢？
