Why can't I put more than one level of
Uncaught Error: Invariant Violation: Relay.QL: Expected query `viewer` to be empty. For example, use `node(id: $id)`, not `node(id: $id) { ... }`.

Why does it do a second query instead of re-using the result?
fragment on Viewer {
files(first: 10) {
edges {
node {
id,
url,
},
},
},
}

"this" is null in my handler. Am I doing something wrong here?

import ReactDOM from 'react-dom';
class FileUploadPage extends React.Component {
