Another YAJLDTAGEN (DATA-GEN) question

I can't figure out how to setup my JSON data structure to produce the following...

[
{
"isAvailable": true,
"itemNumber": "DD03614",
"nextAvailableDate": "2021-10-20T16:58:36.54",
"qtyAvailable": 0
},
{
"isAvailable": true,
"itemNumber": "DD03552",
"nextAvailableDate": "",
"qtyAvailable": 1587
}
]

What's actually produced is:

"item": [
{
"isAvailable": true,
"itemNumber": "DD03552",
"nextAvailableDate": "",
"qtyAvailable": 1587
},
{
"isAvailable": true,
"itemNumber": "DD03614",
"nextAvailableDate": "2021-10-20T16:58:36.54",
"qtyAvailable": 0
}
]
}

I need to remove the "item" name.



I currently have tried several iterations of this (using various %GEN options):
DATA-GEN request %DATA(jsonBody: 'output=clear countprefix=num_')
%GEN('YAJLDTAGEN');

My DS looks like this:

dcl-ds request qualified inz;
num_item int(10) inz;
dcl-ds item dim(5000) inz;
isAvailable ind inz(*off);
itemNumber varchar(15) inz('');
nextAvailableDate varchar(22) inz('');
qtyAvailable int(10) inz(0);
end-ds;
end-ds;
