GraphQL query failing

[markggibson]

Hello! The perfect article at the right time for me at https://dashbird.io/blog/serverless-react-graphql/ but I can't get past adding in the DisplayPosts component into App.js.

I get the following error:
TypeError: this.currentObservable.query.getCurrentResult is not a function. (In 'this.currentObservable.query.getCurrentResult()', 'this.currentObservable.query.getCurrentResult' is undefined)
I've also cloned this repository and can't amplify init gives me init failed

Any guidance welcome
