title: Google Chrome Console Error
body: <p>It's a Shopify App.Shopify that loads my web application on their iframe.
  It works great on Mozila Firefox, IE and other browsers except on Chrome. When I try to load on Chrome, it shows following error.</p>
  
  <blockquote>
    <p>Refused to frame '<a href="http://5281a995.ngrok.io/" rel="nofollow noreferrer">http://5281a995.ngrok.io/</a>' because it violates the
    following Content Security Policy directive: "child-src 'self'
    https://* shopify-pos://*". Note that 'frame-src' was not explicitly
    set, so 'child-src' is used as a fallback.</p>
