Hi VijayKasindala,
There are two potential issues:
1. You are attempting to access the output data of the JSON Parser from the initial snap HTTP Client - Get, so this approach will not work. You can only access the output data of the HTTP Client - Get.
2. According to the HTTP Client Snap documentation, the 433patches21307 update has introduced an issue that changes behavior: "pagination evaluation now occurs before sending the output to the output view".
A workaround for pagination using the HTTP Client Snap has been proposed, and you can find the details at the following link: https://docs-snaplogic.atlassian.net/wiki/spaces/SD/pages/3097822264/Pagination
Hope this helps!
Kind regards,
Ivica.
