localhost/:1 Fetch API cannot load http://localhost:8000/gql. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. The response had HTTP status code 405. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Can you post your code in ./frontend/src/App.js, especially this part here:

class App extends Component {
  render() {
    return (
      <ApolloProvider client={client}>
        [...]
      </ApolloProvider>
    )
  }
}

This may be internal error because once I tested on another computer, it worked and this is reasonable for me because the setting of that computer was a little bit unique. Thanks for the follow up
