如何将赛普拉斯模块 API 与 Next.js 和 Vercel 一起使用

Question

我有一个使用 Next.js 制作的 Web 应用程序部署到 Vercel，我正在尝试使用 Cypress Module API 添加一些夜间测试。我创建了一个端点 api/test，我从中调用 cypress.run() 并执行测试。这在本地（在开发服务器和构建中）都可以正常工作，但是当我部署到 Vercel 并调用端点 api/test 时，它会引发以下错误：

我尝试在 postinstall 中手动运行 cypress install，但错误不断发生。关于 Vercel/Next 修改其构建的方式，我是否遗漏了什么？

我想知道你是否已经解决了这个问题，因为我遇到了同样的问题？
