TypeError:当SSR具有可加载组件和无服务器时，无法读取未定义的__esModule属性/* webpackPrefetch: true */

Question

我正在使用serverless部署一个带有SSR的React应用程序。当我使用loadable-compoennts进行代码拆分时，一切都很好，直到我尝试优先使用资源。向任何可加载方法添加/* webpackPrefetch: true */会导致在导入my < App >时服务器端崩溃

To Reproduce

重现行为的步骤：

git clone https://github.com/agawley/loadable-repro
npm i
npm run offline

加载http://localhost:3000

页面应该加载一个“显示/隐藏”链接，该链接显示延迟加载的组件SomeText。如果您从app.js中删除了/* webpackPrefetch: true */注释，您将获得预期的行为(但没有预取！)
