Group step in Workflow throws java.lang.IllegalArgumentException: Invalid handle
I have a workflow in Experian's Aperture Data Studio (version 184.108.40.206) which unions 24 inputs
From this union, I then have a group step which allows me to see what the validation results are for each category
When I use aggregates, there is no problem but when I group and aggregate together, I get this error thrown:
java.lang.IllegalArgumentException: Invalid handle
The unusual aspect is that I have pretty much a mirror copy of this workflow which is working fine and when I run the combined workflow job, the output is produced without issues.
If there is someone who can help me diagnose this issue, that would be much appreciated

Hi @Curran Sareen
Best thing to do here is to raise a case with your local support team, who will be able to assist: https://docs.experianaperture.io/more/contact-support
For them to be able to investigate, they'll likely need:
In my experience, "Invalid handle" errors originate from the Validate Addresses step, do you have that as part of the workflow?
