  <p>I generated OAuth2 credentials, enabled the Analytics API and entered my credentials in the clientid field under the javascript that I'm running. </p>
  
  <p>I am hosting this basic page locally with Python HTTP server. I added localhost in every format, including "<a href="http://localhost:8080" rel="nofollow noreferrer">http://localhost:8080</a>" and "<a href="http://localhost" rel="nofollow noreferrer">http://localhost</a>" under the credentials' authorized origins and I am still getting the above error. I am stumped. None of the proposed solutions seem to be working as I've followed through with them.</p>
