Google_Activity must be an instance of Google_ActivityObject

Question

I don't know what is the error of this. I might think as well is in the library of google PHP client can someone help with this.

This is my code:

$this->client->refreshToken($con[0]->secret);
$newtoken = $this->client->getAccessToken();
$this->client->setAccessToken($newtoken);

$activityAccess = new Google_Acl();
$activityAccess->setDomainRestricted(true);

$object = new Google_ActivityObject();
$originalContent = $object->setOriginalContent('Happy me');
$originalContent = $object->setContent('Happy me');
$originalContent = $object->setObjectType('domain');

$body = explode(".", $args["post"]);
$activity = new Google_Activity();
$postBody = $activity->setTitle($body[0]);
$postBody = $activity->setVerb('post');
$postBody = $activity->setKind('plus#activity');
$postBody = $activity->setObject($originalContent);
$postBody = $activity->setAccess($activityAccess);

$data = $this->connect->activities->insert('me', $postBody);

This generates the error below. I don't know what exactly the error means.

The error here is that the activity object is not being properly built, hence the error "must be an instance of Google_Activity". There are different ways in which you can build the activity object to insert it as a comment in your G Suite Google Plus profile. Take for example the following approach.

$service = new Google_Service_PlusDomains($client);

$activity = new Google_Service_PlusDomains_Activity(
   array(
      'access' => array(
          'items' => array(
              'type' => 'domain'
          ),
          'domainRestricted' => true
      ),
      'verb' => 'post',
      'object' => array(
          'originalContent' => "Post using Google API PHP Client Library!" 
      ), 
   )
);

$newActivity = $service->activities->insert("me", $activity);    

var_dump($newActivity);

The reference documentation explains what are the required and optional properties the object must have. I strongly recommend you to build the object using an array as explained above. That should make it work. I hope this information helps.
