JSON DS & Data-Into

Hopefully someone can help me with the various DS definitions and the necessary parameters on the Data-Into command.

This is my first experience with JSON as the web guy asked if we can read it or does he have to create another flat file.

This was partially working when I first put together a test pgm using Scott's YAJL and the various subprocedure calls to process JSON. I got the Data-Into PTFs installed (7.3), switched the parser to YAJLINTO and now I'm realizing that my JSON document is complex. There are three JSON "objects" or data structures in the incoming document. It doesn't matter if I have to process the document three times or can do it all once.

The document looks like this:

{"documentHistoryEvents":[{"type":"Created","date":"2019-04-01T20:33:13.485564Z","description":"Created by external_web_esig@xxxxxxx","participantEmail":"external_web_esig@xxxxxxx","actingUserIpAddress":"66.194.20.120"},{"type":"Sent","date":"2019-04-01T20:33:15.048387Z","description":"Sent<mailto:external_web_esig@xxxxxxx%22,%22participantEmail%22:%22external_web_esig@xxxxxxx%22,%22actingUserIpAddress%22:%2266.194.20.120%22%7d,%7b%22type%22:%22Sent%22,%22date%22:%222019-04-01T20:33:15.048387Z%22,%22description%22:%22Sent> by external_web_esig@xxxxxxx","participantEmail":"external_web_esig@xxxxxxx","actingUserIpAddress":"66.194.20.120"},{"type":"Viewed","date":"2019-04-01T20:33:40.774774Z","description":"Viewed<mailto:external_web_esig@xxxxxxx%22,%22participantEmail%22:%22external_web_esig@xxxxxxx%22,%22actingUserIpAddress%22:%2266.194.20.120%22%7d,%7b%22type%22:%22Viewed%22,%22date%22:%222019-04-01T20:33:40.774774Z%22,%22description%22:%22Viewed> by test@xxxxxxx","participantEmail":"test@xxxxxxx","actingUserIpAddress":"66.194.20.120"}],"participants":[{"email":"external_web_esig@xxxxxxx","name":"Program<mailto:test@xxxxxxx%22,%22participantEmail%22:%22test@xxxxxxx%22,%22actingUserIpAddress%22:%2266.194.20.120%22%7d],%22participants%22:[%7b%22email%22:%22external_web_esig@xxxxxxx%22,%22name%22:%22Program> Administrator"},{"email":"external_web_esig@xxxxxxx<mailto:external_web_esig@xxxxxxx>","name":"Program Administrator"},{"email":"test@xxxxxxx<mailto:test@xxxxxxx>","name":"SMILEY ALMENDAREZ"}],"status":"Viewed","documentKey":"Lzq8e8o8tmFYi2viZphuHh"}

There's a documentHistoryEvents, participants, and an unnamed object. It's formatted correctly as I had the web guy show me using one of the online formatters.

My Data structures and code are defined as follow:

Dcl-ds documentHistoryEvents Dim(100) Qualified;
Type Char(20);
Date Char(28);
Description Char(50);
ParticipantEmail Char(50);
ActingUserIPAddress Char(50);
End-Ds;

Dcl-ds participants Dim(100) Qualified;
EMail Char(50);
name Char(50);
End-Ds;

Dcl-ds DocStatus Qualified;
status Char(20);
documentKey Char(50);
End-Ds;

Dcl-s ResponseStr VarChar(16000000);

// Load JSON Document into DS
Data-Into documentHistoryEvents %Data(ResponseStr:'Case=Any -
Doc=String ')
%Parser('YAJLINTO');

ResponseStr has the JSON loaded from a website using an HTTP call. I've tried processing just the documentHistoryEvents document using combinations of path, allowextra and countprefix options, but I keep getting RNX0356 reason code 5 when executing. I understand the layouts of the DS should match the JSON fields but not sure what to do with multiple documents and an unnamed document.
