title: 404 error when refreshing the page - React App deployed on Heroku
body: <p>I deployed a React App on heroku and every time that you refresh some page, a 404 error appears, 
  like: <code>Cannot GET /create</code></p>
  
  <p>I have been searched about it and i found a related issue: 
  <br>
  <a href="https://github.com/mars/create-react-app-buildpack/issues/1" rel="nofollow noreferrer">Question about 404 with React Router</a></p>
  
  <p>So i created a static.json file redirect to the index.html but the error still happening.</p>
  
  <pre><code>{
      "root": "build/",
      "clean_urls": false,
      "routes": {
        "/**": "index.html"
      }
    }
  </code></pre>
  
  <p>Does anyone had the some problem with a react app deployed to heroku?</p>
