auth_id undefined

[loretoparisi]

I have configured the .env file in the root dir of wavesync/ like:

CLIENT_ID=xxxxxxx
CLIENT_SECRET=xxxxxx
REDIRECT_URI=http://localhost:8081/callback
PROJECT_ROOT=http://localhost:8081
NODE_ENV=development

and setup the http://localhost:8081/callback on the spotify developer app settings like here:

I run npm run serve and when I do the login I get a redirect to the url http://localhost:8081/login?auth_id=undefined with a blank page.

I have printed the process.env here to be sure it was ok:

console.log("----",process.env,"----");
router.get('/', (req, res, next) => {
  const auth_id = req.query.auth_id
  const query = querystring.stringify({
    response_type: 'code',
    client_id: process.env.CLIENT_ID,
    scope: 'user-read-playback-state',
    redirect_uri: process.env.REDIRECT_URI,
    state: auth_id
  })

I can see CLIENT_ID and REDIRECT_URI values.
