title: Firebase storage and Invalid HTTP method/URL pair
body: <p>When I try to fetch a firebase storage file using ReactReader, I get the following error:</p>
  
  <pre><code>{
  "error": {
  "code": 400,
  "message": "Invalid HTTP method/URL pair."
  }
  }
  </code></pre>
  
  <p>The code is making a request to <a href="https://firebasestorage.googleapis.com/v0/b/" rel="nofollow noreferrer">https://firebasestorage.googleapis.com/v0/b/</a>....</p>
  
  <p>but that returns the error above.</p>
  
  <p>Has anyone run into this issue?</p>
