I am using getdatasubsetdownloadlinkfromrule and following the steps in documentation.
forum.appian.com/.../Download_DataSubset_Plugin.html

When I complete selecting the filter, URL is getting generated but when I click on the link, 500 - Internal Server Error is showing up. We tried several solution provided in other post but nothing worked. We were forced to move the report to a process model using a different plugin. Attaching the code snippet here. Appreciate any help.

I forgot to report back, but I've figured out my issue.

a!toJson and a!fromJson cause issues when sending through a large datasubset. It seems to have a character limit, because I could send a varying amount of data through, but once it hit the limit (unsure of exact character limit) it would not convert back to a datasubset and it would cause the getdatasubsetdownloadlinkfromrule to break.

What I am doing now is passing just the search criteria in, and then using that to bring back the datasubset at the CTQG_ToExportableDataSubset level instead of passing the datasubset into it.

This means I could not make the exportable data subset rule generic. It's a shame but hopefully this knowledge helps others.

Thanks for your suggestions kumaravein
