Don't know if this is on the Google side of things, in GitKit, or somewhere in your code. The authorization flow (with Google) is failing due to redirect_uri_mismatch. The callbacks are correctly registered, the problem is that the callback URL contains a query string, which Google is failing to recognize as a matched redirect URI.
Is the redirect URI callback URL being assembled in your code or in the broader library? Is this project stale? I see different code examples on the developers.google.com docs.
