but when I define the list type as my transaction field type and run the job.

Hi

The List of Value type is actually a string type, NOT a List type in Java, it is used to select context value from a predefined list before running Job (when checking context checkbox). To build json array, please go to the tip page and read the tip of Step, 7.
