晚 7 点 30 分左右，halo 博客前台无法访问，console 正常，前台控制台抛出 ERR_INCOMPLETE_CHUNKED_ENCODING 200

起初看到 github 上有人有类似问题

https://github.com/halo-dev/halo/issues/5174

但是插件并没有不兼容的现象出现，无奈开始自己排查

进入 docker 容器

ssh 连上服务器后

docekr attach 010

010 是 halo 容器 id 前三位

进入后，刷新前台页面，报错信息如下

        at run.halo.app.theme.finders.impl.MenuFinderImpl.lambda$getByName$1(MenuFinderImpl.java:47) ~[classes/:2.20.13]

注意到

menuFinder.getByName(theme.config.footer.menu) 抛出异常

以及

Menu with name menu-kqhhy not found

问题在于前台获取主题配置中的页脚菜单时空指针了，回忆今天的配置，已经知道哪里踩坑了

问题复现

在 hao 主题中，页脚配置中有这样的设置

这个配置选中就无法取消，然而我觉得这个菜单有点丑，没办法取消就新建了一个空菜单进行了绑定

当天在对博客进行继续扩充内容时感觉这个菜单很碍眼，就给他删了，删除之后，由于浏览器缓存问题，乍一眼前台并无不对，以为删了会自动解绑，晚点修改文章时发现前台已经挂了很久了，根本无法访问，最后定位到这里

总结

不要乱删东西！！！
