Zotero 同步出错，出现“ZoteroObjectUploadError”

- 问题描述

- 我的情况

笔者利用 Zotero 添加一篇arxiv上的文献，发现添加完成之后， Zotero 在同步时出错，如下所示。

点击红色感叹号，查看其错误日志为：

version => 5.0.96.3, platform => Win32, oscpu => Windows NT 10.0; WOW64, locale => zh-CN, appName => Zotero, appVersion => 5.0.96.3, extensions => Zotero LibreOffice Integration (5.0.25.SA.5.0.96.3, extension), Zotero Word for Windows Integration (5.0.19.SA.5.0.96.3, extension), ZotFile (5.0.16, extension)

利用浏览器或者arxiv ID等添加文献，都会同步出错。

查询网络发现，相似的情况如下：

1. zotero 同步问题怎么解决？
2. ZoteroObjectUploadError: ‘’ is not a valid linkMode
3. ZoteroObjectUploadError #12

但是都未能给出解决的方法。

- 解决方法

虽然无法直接解决这个bug，但是笔者还是找到了替代方法——即手动添加文献。
如果在 Zotero 中手动添加失败，还可以去其官网在云空间手动添加文献。

1. 打开 zotero 官网（https://www.zotero.org/）
2. 点击 Web Library ，此时你会进入到你的云空间。
3. 在需要的位置手动添加文献。
   
   亲测有效。
