title: Firebase Storage sample with 400 error
body: <p>It seems the Storage sample [<a href="https://github.com/firebase/quickstart-js]" rel="nofollow">https://github.com/firebase/quickstart-js]</a> sample has 400 error.</p>
  
  <blockquote>
    <p>Failed to load resource: the server responded with a status of 400 (OK)</p>
  </blockquote>
  
  <p>It seems the api key is wrong, but I actually copy it from firebase console.</p>
  
  <p>My alive demo is here: <a href="https://fir-storage-25695.firebaseapp.com/" rel="nofollow">https://fir-storage-25695.firebaseapp.com/</a></p>
  
  <p>Thanks,</p>
