Authorization should be passed not AuthorizationReactND

[osama-alrefai]

in server.js, it says

app.use((req, res, next) => {
  const token = req.get('Authorization')

  if (token) {
    req.token = token
    next()
  } else {
    res.status(403).send({
      error: 'Please provide an Authorization header to identify yourself (can be whatever you want)'
    })
  }
})

note: Authorization is required, not as per documentation AuthorizationReactND
