I'm attempting to do the "hello world" here: https://github.com/howtographql/react-relay . I ran the init script and got the error that models User, Link, and Vote were missing the "@model" directive. So, I added the "@model" to the local schema, and re-ran. Now, it says only the "User" model is missing the "@model" directive, which is progress, I suppose. But, I'm stuck here.
