I'm using

jet_cct_api_query('places',array(
	'field' => 'cct_single_post_id',
	'operator' => '=',
	'value' => get_the_ID(),
	'type' => 'auto',
    ),1,0,array('orderby' => 'cct_single_post_id',
	 	'order'   => 'desc',
	 	'type'    => 'auto',));

and it's returning an empty array. What am I doing wrong?

Thank you. This is very useful!
