DATA-INTO Error RNX0356 (json)

[Greg Wilburn <gwilburn@xxxxxxxxxxxxxxxxxxxxxxx>]

I'm consuming a relatively new web service... just wondering if the error I'm getting is due to my poor coding, or their poor implementation.


Message . . . . :   The document for the DATA-INTO operation does not match
  the RPG variable; reason code 4.
The exact subfield ..
json.response(1).repgroupretailermanufacturers.accountnumber

UGGHHH...

My DS looks like this...

...more above
      num_repgroupretailermanufacturers uns(5) inz(0);
      dcl-ds repgroupretailermanufacturers;
        accountnumber varchar(10) inz('');               // This is our Customer Number
//        minimumorderamount varchar(1) inz('');
//        minimumreorderamount varchar(1) inz('');
//        shipToAccountnumber varchar(1) inz('');
      end-ds;
...more below

  dcl-c  RPGOPTS  const('doc=file case=convert allowextra=yes countprefix=num_');
  dcl-c  YAJLOPTS const('{ "value_null": "", "document_name": "json"}');

    monitor;
      Data-Into json %data(inStmf:RPGOPTS) %parser('YAJLINTO':YAJLOPTS);
    on-error;
      ouErrors = 1;
      return;
    endmon;

The JSON array causing the error normally looks like this:

      "repGroupRetailerManufacturers": {
        "accountNumber": "10434741",
        "minimumOrderAmount": 250,
        "minimumReOrderAmount": 250,
        "shipToAccountNumber": null
      },

However, this document contains:

      "repGroupRetailerManufacturers": null,


Short of having a NUM_ variable in front of EVERY element, is my only option to do allowmissing=yes??
(I can "feel" Jon Paris leaning over my shoulder while I code) LOL
