Hi Zohaib,
It seems the attached sample data is missing. Could you please the same at support@shephertz.com?
Also, could you please share the code snippets in which you are getting this problem along with the SDK internal logs?
It will help us to understand the problem you are facing.
P.S. To enable SDK internal logs, please add following code just after initialising App42API:
[App42API enableApp42Trace:YES];
Regards,
Rajeev
