Exception while using Windowing Aggregator

@swayam The Jira states that this issue happens when there are some data rules created and the workaround would be to delete those. 

Hi @Sanjeev 

“there are some data rules created” - I’m unable to understand what data rules it is reffering to? My pipeline is as below:

@swayam here’s the link to the docs that explains data rules - https://docs.streamsets.com/portal/#datacollector/latest/help/datacollector/UserGuide/Alerts/RulesAlerts_title.html#concept_tpm_rsk_zq

If you don’t have the data rules defined, perhaps the issue is caused by something else. 

Thanks - actually there is no “Data Rules’ that is configured in pipeline. So the actual cause of the issue is still unknown and there is no elegant recovery from this.

Regards

Swayam
