Gmail PHP API Create Filter Issue - php

Question

Am trying to use the official Gmail PHP Library to create a new label. I am using standard Oauth to authenticate the user (all necessary permissions have been given).
But I receive the following error:
<b>Fatal error</b>: Uncaught exception 'Google_Service_Exception' with message '{
"error": {
"errors": [
{
"domain": "global",
"reason": "invalidArgument",
"message": "Filter doesn't have any actions"
}
],
"code": 400,
"message": "Filter doesn't have any actions"
}
}
The code is as follows:
$gmail = new Google_Service_Gmail($google);
$label = new Google_Service_Gmail_Label();
$label->setId('Label_8');
$label2 = new Google_Service_Gmail_Label();
$label2->setId('UNREAD');
$label3 = new Google_Service_Gmail_Label();
$label3->setId('INBOX');
$criteria = new Google_Service_Gmail_FilterCriteria();
$criteria->setFrom('test#gmail.com');
$action = new Google_Service_Gmail_FilterAction();
$action->setAddLabelIds(array($label));
$action->setRemoveLabelIds(array($label2,$label3));
$filter = new Google_Service_Gmail_Filter();
$filter->setCriteria($criteria);
$filter->setAction($action);
$result = $gmail->users_settings_filters->create('me',$filter);
Scopes being set:
$google->setScopes(array('https://www.googleapis.com/auth/pubsub','https://mail.google.com','https://www.googleapis.com/auth/gmail.settings.basic'));
Everything looks fine programmatically. I even checked the code and it is assigning the actions. I believe there maybe something wrong with the library. Any advice will help.

Answer 1

Found the issue by analyzing the logs:
$action->setAddLabelIds(array($label));
$action->setRemoveLabelIds(array($label2,$label3));
Should be:
$action->setAddLabelIds(array('Label_8'));
$action->setRemoveLabelIds(array('UNREAD','INBOX'));
Inconsistent API at the moment.
