TypeError: Cannot read property 'token' of undefined

Question

I am facing this error : TypeError: Cannot read property 'token' of undefined - Here's a link! to my github page

I am using a firefox addon to post data and sending data in json format like: {"x-access-token": "jashiuahf"}

Here is the image enter image description here @fabio

Can anybody help me solve this please!!!

Answer 1

It looks like the error comes from these lines

app.use(function(req, res, next) {
console.log(req.headers['x-access-token']);
var token = req.body.token || req.body.query || req.headers['x-access-token'];
........ more code ....

I think that req.body.token or req.body.query is not the place to look for authentication or access token, always try to look for it in the request header. The error is because token is not a property of req.body, just

var token = req.headers['x-access-token'] || '';

should work.

Answer 2

I also faced the same error while working with Node and Express..

Turns out I didn't require cookie-parser dependency at the top make sure you require and mount it

const cookieParser = require('cookie-parser');
app.use(cookieParser());
