Steps to reproduce the issue

1. Step1: Set JConfig $dbtype = 'pdomysql';

2. Step2: Insert new record to db

    $session = JFactory::getSession();
   $objectUpload = new stdClass();
   $objectUpload->Id = null;
   $objectUpload->machine_id = UploadHelper::getMachineId();
   $objectUpload->file_list = json_encode([$attachment]);
   $objectUpload->session_token = $session->getId();
   $objectUpload->attachment_key = $attachmentKey;
   $objectUpload->attachment_type = $attachmentType;
   $objectUpload->status = $isInitialize == 'true' ? 0 : 4;
   $objectUpload->add_timestamp = time();
   
   $result = JFactory::getDbo()->insertObject('#__upload_queue', $objectUpload, 'Id');
   

Expected result

    $result=>Id > 0

Actual result

    $result=>Id  == 0
