Reg: Issue with RPG Service Program which is used for IWS

Hi All,

I am facing this weird issue which I am not able to identify using the job
log. It will be more helpful if anyone points me in the right direction to
identify the issue.

I created a Service Program which I will configure in IWS Service. Whenever
a request comes from the External world this Service program is the first
program which will be executed.

I am getting the input in JSON format and I am using the DATA-INTO and
DATA-GEN opcodes in the Service program module for parsing and generating
the JSON.

Now, in the Service program module i have one of the below line

data-gen DS_Input %data(Wrk_Input:'doc=string countprefix=num_')
%gen('YAJLDTAGEN');

I am getting this error while executing this code,

Pointer not set for location referenced.
Error caused procedure _QRNI_GLOB in program LIBL/YAJLDTAGEN to stop
during initialization.
Error RNX8001 occurred while running the program or procedure for the
DATA-GEN operation.

Any response will be very much appreciated.

Regards,
Suren
