RT GSync: Google Calendar, Contacts, Drive Sync

Installed GSync and when I ran cron.php (via command line) for the first time I got this error, and I'm sure it wasn't supposed to happen any errors, right? ~~~ $ php -f cron.php PHP Notice: Undefined index: gContact$groupMembershipInfo in /home/user/mydomain.com/custom/include/Google/ContactHelper.php on line 43 PHP Stack trace: PHP 1. {main}() /home/user/mydomain.com/cron.php:0 PHP 2.
