maaaaabye this?

index.js

let next = require('../../front/.next/serverless/pages/index.js')

exports.handler = async function http(req) {
  req.url = req.path
  let res = {end(){},setHeader(){}}
  return {type:'text/html; charset=utf8', body: next.render(req,res).html}
}

Running that I can see that the renderReqToHTML function in Next does get the html string, but it's not showing up on the page or in the end(){} function.

I wrote this which is janky as heck, but it gets the right html to the browser. The right html makes it to the res.end() function, but nothing returns. I'm not sure how to mock the real res.end() function

exports.handler = async function http(req) {
  let html
  let res = {
    method: 'GET',
    headers: [],
    statusCode: 400,
    getHeader: (val) => {
      console.log("getHeader", val)
      return true
    },
    setHeader: (header, content) => {
      this[header] = content
      console.log("this is header", header)
      return header
    },
    end: (end) => {
      console.log("This is what end gets", end)
      html = end
      return end
    }
  }
  req.url = req.path
  const body = await next.render(req, res)
  console.log("this is body", body)
  return {
    type: 'text/html; charset=utf8',
    body: html
  }
}
