title: Helmet errors with renderStatic
body: <p>I'm trying to setup Helmet npm using SSR within my meteor application and I'm getting the error, <code>Error running template: TypeError: Cannot read property 'renderStatic' of undefined at sink</code>. I'm new to using SSR so I'm not following what I'm missing here. Very nooooob question.</p>
  
  <p>Path: <code>server/main.js</code></p>
  
  <pre><code>import React from "react";
  import PropTypes from 'prop-types';
  import { onPageLoad } from "meteor/server-render";
  import { renderToNodeStream } from "react-dom/server";
  import { ServerStyleSheet } from "styled-components"
  import { Helmet } from 'react-helmet';  
  
  import App from "/imports/server/app/App";
  
  onPageLoad(sink =&gt; {
    const sheet = new ServerStyleSheet();
    const appJSX = sheet.collectStyles(
      &lt;App location={sink.request.url} /&gt;
    );
  
    App.propTypes = {
      location: PropTypes.object,
    };
  
  
    const htmlStream = sheet.interleaveWithNodeStream(
      renderToNodeStream(appJSX)
      );
  
    sink.renderIntoElementById("react-root-app", htmlStream);
  
    const helmet = Helmet.renderStatic();
    sink.appendToHead(helmet.meta.toString());
    sink.appendToHead(helmet.title.toString());
  
  });
  </code></pre>
