Sunird 很老的版本了。。最近按照文档做了迁移先升级到0.4.4然后导出json,也复制了upload文件夹。安装最新版本导入json显示成功，后台报错“Caused by: java.nio.file.NoSuchFileException: /tmp/undertow3568791523374871132upload”。 应该是找不到路径已经确认upload在~/.halo文件夹下。请问这种情况下可能是什么原因？怎么解决~~感谢感谢😃😀@

duia johnniang nginx 的 client_max_body 已经配置过了，没报错了，是后台日志报错了，就是楼主三层展示的错误，异常信息一样。本地没问题，本地迁移完把h2的数据文件上传到了服务器。现在是这样解决的。
