Cannot use ‘parent’ in a class with no parent

I am trying to extend the MagentoFrameworkAppActionHttpPostActionInterface class and my construct looks like this:

public function __construct(
    MagentoFrameworkAppActionContext $context,
    MagentoFrameworkViewResultPageFactory $pageFactory,
    MagentoFrameworkMessageManagerInterface $messageManager,
    MagentoFrameworkHTTPClientCurl $curl,
    MagentoFrameworkFileUploaderFactory $uploaderFactory)
{
    $this->_curl = $curl;
    $this->messageManager = $messageManager;
    $this->_pageFactory = $pageFactory;
    $this->uploaderFactory = $uploaderFactory;
    return parent::__construct($context);
}

I am getting an error though on this line return parent::__construct($context);

Cannot use ‘parent’ in a class with no parent.

How else should I write the return line then?
