Getting an issue with email_content property. When creating object it is defined and when dumping the object I can see the property.
$campaign = new Campaign();
$campaign->name = 'A name';
$campaign->subject = 'a subject';
$campaign->from_name = 'a name mail';
$campaign->from_email = 'delivery@mail.com';
$campaign->greeting_string = '';
$campaign->reply_to_email = 'to@mail.com';
$campaign->text_content = '<html><body>' . $message . '</body></html>';
$campaign->email_content = '<html><body>' . $message . '</body></html>';
$campaign->email_content_format = 'HTML';
$campaign->addList($delivery_list);
$campaign = $this->cc->emailMarketingService->addCampaign(ACCESS_TOKEN, $campaign);After the addCampaign I get the error email_content: Property is required but not found.
