Hi,

 As per business requirement, run cron job after specific interval of time. I am using REST API in custom scripts in custom report. I tested the same code in different PHP file and I am able to get results. I need to get all the result in PDF file format and send it to my email id with attachment. I am getting error "Root Element Missing" after running custom report.  Here is what I have written in different tabs.

Initialization Tab

require_once(get_cfg_var('doc_root')."/ConnectPHP/Connect_init.php");
