Just getting "[contact-form]" output

I’m building an XML file where I’d like to parse the output HTML form for use in a non-browser application.

I’m having trouble, however, as the output of the form is only “[contact-form]” from this code:

echo apply_filters('the_content', get_page(2)->post_content);

I’m using the Jetpack version of the plugin. Please help
