Error during WebSocket handshake: Unexpected response code: 200

I saw similar errors for code 400 and 404, but this one seems strange. After all, I would think a 200 code would mean “everything’s ok” right?

"peer": "^0.5.1", "peerjs": "^1.2.0"

On server side:

import { ExpressPeerServer } from 'peer'

const PeerController = {}

PeerController.initialize = function (app) {
  const peerServer = ExpressPeerServer(app, { debug: true, path: '/peerjs' })

  peerServer.on('connection', (client, foo) => {
    console.log(client, foo)
  })

  return peerServer
}

export default PeerController

const app = express()
app.use('/peer', PeerController.initialize(app))

And on the client side (a Vue application):

import Peer from 'peerjs'
export default {
  name: 'Meet',
  data () {
    return {
      peer: null
    }
  },
  mounted () {
    this.peer = new Peer('12345', {
      host: '/',
      port: '3000',
      path: '/peer/',
      debug: 3
    })
    this.peer.on('error', (err) => {
      console.debug(err)
    })
    this.peer.on('open', function (id) {
      console.log(id)
    })
  }
}

vendor.3921cbfb.js:18 WebSocket connection to 'ws://localhost:3000/peer/peerjs?key=peerjs&id=12345&token=697lo3pxz52' failed: Error during WebSocket handshake: Unexpected response code: 200

I noticed that it was 404ing initially until I added the path: '/peerjs' in the ExpressPeerServer constructor, because it seems that no matter what the client library tries to hit that endpoint. Not a huge worry, but after I solved the 404 issue I now get an “error” with a 200 code. Any advice? Thank you very much…

Looks like using the look-ahead regex worked. Might be handy to also allow passing in app instead of server, so that this is easier to handle. But thank you for your assistance!
