Issue on syncing Google Contacts via cron

[stefkev]

Hi,

I am having issue on creating a cron job on google contact upload.

I use following function to dispatch a task

$collection = $this->getEntityManager()->getRepository('Contact')->where(array('deleted' => false))->find();
try {    
$gc = new GoogleContacts($this->getContainer());
   foreach($collection as $contactData) {
        array_push($data->idList, $contactData->id);
        $gc->actionPush(null, $data, null);
    }
 }catch (\Exception $e) {
    $GLOBALS['log']->error('GoogleContactSync: Run Sync Error: ' . $e);
} 

Keep in mind that in data, entityType is set to Contact, and idList is set of contact id's fetched from database.
I get issue following issue on executing the task:

Error Details: Call to a member function getContactsClient() on null. All linking to google contact is set properly, and when i do manual push of data it works.
