The components guide isn't really clear on exactly how to use this component. Here is my scenario...

I have a CSV file coming in that contains 6 columns:

Name, Description, Attribute 1, Attribute 2, Attribute 3, Attribute 4

My goal is to populate another file that contains three columns

Name, Description, Attributes

The Attributes column needs to contains a the JSON output from the Attribute columns in the original file. I do get this output, however the Name and Description columns are ending up null in the final output. I tried adding these to the Group By list, however that didn't make a difference.

Do I have to define ALL fields in the JSON tree, and those in GroupBy will be taken out of the JSON-formatted output?
