Node.js React: cannot add property context, object does not expand

I am currently trying to implement an isomorphic react component in my node.js + express layout. However, when I try to include the specified component in my jade template to render it, I get this error: TypeError: Cannot add property context, object does not expand

Here is my routes file:

var express = require('express');
var router = express.Router();


var React = require('react/addons'),
  ReactApp = React.createFactory(require('../../react/components/ReactApp'));

/* GET home page. */
router.get('/', function(req, res, next) {
  var reactAppEl = ReactApp();
  console.log(reactAppEl);
  var reactHtml = React.renderToString(reactAppEl);
  res.render('index', { reactOutput: reactHtml });
});

module.exports = router;

      

        
        
        
      

    

Component:

/** @jsx React.DOM */

var React = require('react/addons');

/* create factory with griddle component */
var Griddle = React.createFactory(require('griddle-react'));

var fakeData = require('../data/fakeData.js').fakeData;
var columnMeta = require('../data/columnMeta.js').columnMeta;
var resultsPerPage = 200;

var ReactApp = React.createClass({

  componentDidMount: function () {
    console.log(fakeData);

  },
  render: function () {
    return (
      <div id="table-area">

        <Griddle results={fakeData}
                 columnMetadata={columnMeta}
                 resultsPerPage={resultsPerPage}
                 tableClassName="table"/>

      </div>
    )
  }
});

/* Module.exports instead of normal dom mounting */
module.exports = ReactApp;

      

        
        
        
      

    

Also my gulp task raises a warning Warning: Component (...): No method render

on returned component instance: you may have forgotten to define render

in your component, or you may have accidentally tried to display an element whose type is a function that is not a React component ... Warning. Don't set the props property of the React element. Instead, provide the correct value when you initially create the item.

Can anyone help me? Many thanks
