导出表格到excel报错

请专家帮分析一下看什么问题，怎么解决？   页面上做了个导出到excel命令按钮，发布到服务器上后点击导出报错，报错信息见附图，在设计器上运行测试，出现如下报错信息（1、版本7.0.103；  2、同一个工程另外一个页面上的导出按钮可以正常使用）：
因文件有外联数据库就先不往上发了。
在执行导出操作时，未知的异常出现。请再次尝试。{  "ClassName": "System.AggregateException",  "Message": "One or more errors occurred.",  "Data": null,  "InnerException": {    "$type": "Newtonsoft.Json.JsonSerializationException, Newtonsoft.Json",    "ClassName": "Newtonsoft.Json.JsonSerializationException",    "Message": "Error resolving type specified in JSON 'Forguncy.CustomMenu.ForguncyTreeCellType, Forguncy.CustomMenu'.

附上导出报错Demo

我这边使用7.0.104.0版本的设计器打开是可以正常导出的，您也可以使用104版本的设计器再试试呢，另外，导出报错也有可能和浏览器有关，测试时最好使用chrome或者Edge浏览器。
如果仍然有问题可以继续在帖子中跟进哟~

您好，这个问题还需要看一下您工程中具体是怎么设置的，建议您可以附上一个可以复现问题的demo，这边具体帮您看一下哦~

改用7.0.104.0版本的设计器打开后可以正常导出了，看来是新版本更香啊！
示例文件中因为有些公司业务数据信息，问题解决了我就删除了

不客气，问题解决了就好
另外，像这种附件，您可以在上传的时候将权限设置为150（也就是超级版主用户组），这样就只有活字格技术人员可以浏览您的附件，问题解决后再删除附件就可以啦~
