I'm using the React 16 beta (react-fiber) with server side rendering

What I am to understand this to mean?

warning.js:36 Warning: Did not expect server HTML to contain a <div> in <div>.

Answer

Just change express response from

<body>
    <div id="root">
        ${markup}
    </div>
</body>

<body>
    <div id="root">${markup}</div>
</body>

Remove space between tags
