Per https://apiwiki.twitter.com/HTTP-Response-Codes-and-Errors: status code 401 means the authentication credentials were missing or incorrect. Make sure you're successfully connecting via OAuth.

I was facing the same problem. But signing out and then signing in again worked for me. Now my app is working and error is removed.
