nuxt v2 和 firebase 函数的部署错误

当我尝试在 firebase 函数中渲染 nuxt 时，出现“用户代码加载失败。无法确定后端规范”错误。

其他功能都可以部署，但是无论模式是SSR还是SPA，只有nuxt功能失败。

我查看了日志，没有发现任何有用的信息。

当我查看“无法确定后端规范”错误时，我找不到其他人有相同的错误，所以我自己无法找出解决方案。

如果有人可以帮助我，如果你能告诉我如何解决这个问题，我将不胜感激。

谢谢。

函数/index.js：

const functions = require('firebase-functions')
const { Nuxt } = require('nuxt')

const config = require('./nuxt.config.js')
const nuxt = new Nuxt(config)

exports.nuxtServer = functions.https.onRequest(async (request, response) => {
const result = await nuxt.renderRoute(request.originalUrl, { request })
response.send(result.html)
})
