Invalid Auth Token with Rails, Graphql, Apollo Client

Question

I am trying to get a basic Rails, Graphql, Apollo-Client setup working but having trouble with 422 errors 'invalid auth token' on the rails side.

Does my use of apollo look wrong?

It is a Rails 5 app with graphql gem and apollo client.

const csrfToken = document.getElementsByName('csrf-token')[0].content
const client = new ApolloClient({
  networkInterface: createNetworkInterface({
    uri: '/graphql',
    credentials: 'same-origin',
    headers: {
      'X-CSRF-Token': csrfToken
    }
  }),
});
client.query({
query: gql`
    query Camillo2 {
      user {
        id
        email
        created_at
      }
    }
  `,
})
.then(data => console.log(data))
.catch(error => console.error(error));  

Rails log:

Started POST "/graphql" for ::1 at 2017-03-10 08:51:58 -0800

Since Apollo 2.0 and according to

https://github.com/apollographql/apollo-client/blob/master/Upgrade.md

Just do this way

const csrfToken = document.querySelector('meta[name=csrf-token]').getAttribute('content');
const client = new ApolloClient({
    link: new HttpLink({
        credentials: 'same-origin',
        headers: {
            'X-CSRF-Token': csrfToken
        }
    }),
    cache: new InMemoryCache()
});
