我正在尝试使用 Next.js 和我的自定义后端与 Django 开发 Next.js 应用程序。我已经完成了它开发我想要的一切但是当我尝试将它部署到 Vercel 时它给我 getStaticPaths 错误每次我这样做，但是我尝试制作我可以使用 Next.js 和动态路由它工作正常，没有任何问题。

你能帮我吗，因为这是开发我的博客应用程序的最后一步

我遇到的错误 =>

你serverDomain的总是serverDomain = 'http://127.0.0.1:8000'，因为domainName.isInDevelopement总是"True"（作为一个字符串类型，它并不公平）。

因此，您基本上是在尝试从 localhost 获取，但是 Vercel localhost 没有任何内容，python 后端没有在那里运行。
