Nuxt.js: npm start error 【serve/index.js params promise is undefined】

[zlgb-wow]

Version

v2.3.2 (koa)

Reproduction link

init project

Steps to reproduce

1. npx create-nuxt-app nuxt-demo
2. npm install
3. npm run build
4. npm start
5. Server side reported promise. Then method not found, in the server/index.js print, found the promise parameter is undefined
   

   What is expected ?

Hope NPM start works properly

What is actually happening?

app.use(ctx => { ctx.status = 200 return new Promise((resolve, reject) => { ctx.res.on('close', resolve) ctx.res.on('finish', resolve) nuxt.render(ctx.req, ctx.res, promise => { // **promise is undefied** promise.then(resolve).catch(reject) }) }) })

Additional comments?

I hope the authorities can pay attention to it, which leads to difficulties in deployment

Same issue here. Could you fix this problem?

[hassan-jahan]

I created a new Nuxt project then copied its /server folder to the current project.

It was fixed now!

nuxt.render is a reference of connect.js app, unfortunately there is no promise as a parameter of the callback, so you may try:

app.use((ctx) => {
  ctx.status = 200
  return new Promise((resolve, reject) => {
    ctx.res.on('close', resolve)
    ctx.res.on('finish', resolve)
    nuxt.render(ctx.req, ctx.res, err => err ? resolve() : reject(err))
  })
})

And about your code, is it from any official Nuxt module or repo ? If so, could you please send me the link and I'll fix it.
