Vercel 上的 Nuxt API 出现错误“不支持 ES 模块的 require()”，但我没有使用它

Question

好吧，标题说明了一切。

我正在尝试使用 nuxt 构建一个应用程序并将其部署在 Vercel 上。 这个应用程序将有一些我使用 express 的路线（下面的代码），在本地，一切正常，但是当我在 Vercel 上部署时，它说：

RequestId: 114b59a0-d9b3-4ca3-89ef-5703822b9375 Error: Runtime exited with error: exit status 1
Runtime.ExitError
2022-09-27T17:16:24.924Z    undefined   ERROR   Error [ERR_REQUIRE_ESM]: require() of ES Module /var/task/node_modules/got/dist/source/index.js from /var/task/api/index.js not supported.
Instead change the require of /var/task/node_modules/got/dist/source/index.js in /var/task/api/index.js to a dynamic import() which is available in all CommonJS modules.
  at Object.<anonymous> (/var/task/api/index.js:8:35)
  at async Promise.all (index 0)
  at async getListener (/var/task/___vc/__launcher.js:37:11) {

  }
RequestId: 96cd13b3-0e95-4f78-b07c-eeb36593faab Error: Runtime exited with error: exit status 1
Runtime.ExitError

问题是：我没有在我的路线上使用 require，我正在使用 import。

我的代码：

vercel.json

{
  "version": 2,
  "rewrites": [
    { "source": "/api/(.*)", "destination": "/api" }
  ],
  "builds": [
    {
      "src": "api/**/*.js",
      "use": "@vercel/node"
    },
    {
      "src": "nuxt.config.js",
      "use": "@nuxtjs/vercel-builder",
      "config": {
        "serverFiles": ["api/**"]
      }
    }
  ]
}

nuxt.config.js

export default {
  serverMiddleware: [
    '~/api/index'
  ],
}

index.js

import express from 'express';
const app = express()

app.get("/getPlayerProfileInfos", async (req, res) => {
  res.status(200).json({
    userName: 'Steam_User',
    profileUrl: 'https://store.steampowered.com/',
    userProfilePic: 'https://avatars.akamai.steamstatic.com/123.jpg',
    profileCreated: 1234567890,
    countryCode: 'BR'
  });
})

app.get("/getPlayerGames", async (req, res) => {
  res.status(200).json({
    gameList: [
      {
        "appid": 92,
        "name": "Codename Gordon",
        "playtime_forever": 0,
        "achievements": { "total": 20, "achieved": 8 },
        "price": { "actual": 80, "lowest": 13 }
      },
    ],
    totalGames: 20,
    totalGamesPlayed: 10,
    gamesPlatined: 10,
    totalHoursPlayed: 10,
    accountValue: 10,
    lowestAccountValue: 10
  });
})

export default {
  path: '/api',
  handler: app
}
