Re: Reg: JSON Parsing Error when using Scott Klement's YAJL Parser

Hi Suren,

When you get the error, place the cursor on the "Pointer not set for location referenced." error and press F1. That will help pinpoint the error.

It probably isn't important but you characterized your scenario #2 as
adding another array to the document. You haven't added to an array,
you added a second object to the "data" object. It's just semantics,
but it alters the view of the JSON a bit.

I haven't worked with YAJL all that much but within the object you have
two objects, metadata and data and within the data object in your second
scenario, you have two objects, playerPin and playerProfile. I would
guess that adding a second object shouldn't affect the prior reference:

Scenario 1

data.playerProfile

Scenario 2

data.playerPin

data.playerProfile

Maybe giving us the error message would help us track down the solution....

Hi Everyone,

I am using the Scott Klement's YAJL parser for Parsing the JSON

Document. I

am receiving an error when i parsing a document. Let me explain it in two
scenario, Scenario 1 (I can Parse the JSON Document) and Scenario 2 (I
cannot Parse the JSON Document which i am receiving an Error)

Scenario 1: (Parsed Successfully)
JSON Document:
{
"metadata":{
"propertyId":"E4",
"suren":"suren",
"clientId":"ATRIENTKIOSK",
"transDateTime":"2017-11-30T18:25:08Z",
"transStation":"DEVICE1",
"transEmployee":"MASTR"
},
"data":{
"playerProfile":{
"title":"Mr",
"firstName":"John",
"lastName":"Smith"
}
}
}

Data Structure:
Dcl-Ds playerProfile qualified;
title char(5);
firstName Char(25);
lastName char(25);
End-Ds;

RPG Code for Parsing this document
data-into(E) playerProfile %DATA(Wrk_Json: case=convert doc=string
path=json/data/playerProfile allowmissing=yes allowextra=yes)
%PARSER('YAJLINTO' :'{ "document_name":

"json",

"value_null": " " }');
This one works fine.

Scenario 2: (Unable to Parse, got an Error while Parsing)

Add one more array in the document and trying to parse the same
playerProfile i am getting error. Sample as below
JSON Document:
{
"metadata":{
"propertyId":"E4",
"suren":"suren",
"clientId":"ATRIENTKIOSK",
"transDateTime":"2017-11-30T18:25:08Z",
"transStation":"DEVICE1",
"transEmployee":"MASTR"
},
"data":{
"playerPin":{
"pinNumber":"7924"
},
"playerProfile":{
"title":"Mr",
"firstName":"John",
"lastName":"Smith"
}
}
}

Data Structure:
Dcl-Ds playerProfile qualified;
title char(5);
firstName Char(25);
lastName char(25);
End-Ds;

RPG Code for Parsing this document
data-into(E) playerProfile %DATA(Wrk_Json: case=convert doc=string
path=json/data/playerProfile allowmissing=yes allowextra=yes)
%PARSER('YAJLINTO' :'{ "document_name":
"json", "value_null": " " }');

This Scenario Errored Out.

Could you please someone let me know whether this scenario is not handled
in YAJL Parser or am i doing something wrong?

Regards,
Surender K
