502 Bad Gateway在生产环境中使用Nextjs next-auth和URL '/api/auth/callback/cognito'

我正在尝试发布一个使用'next-auth'和aws Cognito的nextjs应用程序。

当我在本地运行时，无论是使用next dev还是next start都能正常工作。

但是当我在生产服务器上运行（使用nginx的ubuntu服务器）时，就无法正常工作。

具体错误：

在访问Cognito内置登录页面后，重定向URL https://...../api/auth/callback/cognito?code=......&state=..... 显示了nginx的默认502错误页面。

我已经检查了以下内容：

• 关于此主题的每一个谷歌搜索结果、GitHub问题和Stack Overflow问题
• 生产环境下的next服务器和nginx服务器的错误日志，没有发现任何问题
• 浏览器控制台日志，也没有发现任何问题

是的，在AWS Cognito中应用程序的Callback URL(s)设置为正确的URL（https:// ....... /api/auth/callback/cognito）。

代码：

middleware.ts

export { default } from "next-auth/middleware";
export const config = { matcher: ["/dashboard/:path*"] };

next.config.js

const nextConfig = {
  reactStrictMode: true,
  swcMinify: true,
  compiler: {
    styledComponents: true,
