What happened?

I have created one pipeline which has "Data grid" and "Enhanced Json Output" tranforms.

Inserted 4 records into datagrid.
Enhanced json output configuration: In General tab selected "Output value" in operation dropdown.
Group Key tab : Id selected
Fields tab : Firstname, middlename,lastname
