调用 /blade-system/dict/dictionary-tree接口 返回异常

一、该问题的重现步骤是什么？

1. 系统字典新增数据，在字典详情中增加子项

2. 调用 /blade-system/dict/dictionary-tree接口

3.接口返回

    {

      "code": 500,

      "success": false,

      "data": {},

      "msg": "null key in entry: null=DictVO(id=null, parentId=null, children=[], parentName=null)"

    }

二、你期待的结果是什么？实际看到的又是什么？

数据正常返回

三、你正在使用的是什么产品，什么版本？在什么操作系统上？

商业版本2.7

四、请提供详细的错误堆栈信息，这很重要。
