How to access req object in resolver using express?

[yosletpp]

I'm tying to make an graphQL endpoint in a already existing express project, Have a authentication middleware that evaluates the token and attach user object to req (req.user) I want to be able to get this user in the resolver. example:

....
import { createHandler } from 'graphql-http/lib/use/express';
....

const schema2 = buildSchema(`
  type Query {
    hello: String
  }
`);

const root2 = {
  hello: (args, context, info) => {
    console.log(context.user);
    // some logic with the user here
    return 'Hello, world!'
  },
};

router.post(
  '/business2',
  createHandler({
    schema: schema2,
    rootValue: root2,
    context: (req) => ({
      user: req.user
    })
    // Pass req.user into the context,
  })
);

if I import createHandler like this

const { createHandler } = require('graphql-http/lib/use/express')

req.user is undefined

but if I import createHanlder like this:

const { createHandler } = require('graphql-http')

I get req.user correctly but, the endpoints gives me timeout.

What is the proper way to do this?? Thanks so much in advance.
