Does this issue have any update?

我寻思这个不是目标函数内部实现吗

### 背景： 我们当前的case是由于一些问题（比如接口的变动导致一些数据不存在，但是未及时处理等），很可能在子应用内会产生一些渲染错误，为了避免影响到其他子应用和子应用内的其他页面，需要在子应用层面启用errorboundary，我们希望能够通过主应用传入AppRoute的error component来管理这个errorBoundary。 ### 设计方案： 我们朴素的想法是通过和renderNotFound相似的方式，通过事件进行通信，由子应用通过在ErrorBoundaryFallback中调用renderError来调起主应用传入的error component页。 PR: [feat: add renderError method to icestark/app](https://github.com/ice-lab/icestark/pull/661)

还没写文档...我抽空加一下

另外 由于配置了sourceMap，所以如果通过ip访问依然会在sourceMap的作用下访问到localhost，并报错： Access to script at 'http://localhost:2337/js/src_pages_xxxxx_index_tsx-src_pages_xxxx_api_ts--857fc7.js' from origin 'http://xxxx.test.xxx.qa' has been blocked by CORS policy: The request client is not a secure context and the resource is in more-private...
