Netsuite restlet: src property must be a valid json object - netsuite

Question

I'm attempting to write a RESTlet script to pull over some work order data to another web application (Tulip), but when I attempt to run the script, I receive the following error output:
"src property must be a valid json object"
My get request does have the "Content-Type: application/json" header.
Here is the script I'm attempting to run for reference (the script is very basic at the moment as I just try to figure this all out):
function getWOSoftLock(){
var WOColumns = new Array();
WOColumns[0] = new nlobjSearchColumn('tranid');
WOColumns[1] = new nlobjSearchColumn('status');
var filter = new nlobjSearchFilter(
'status',
null,
'is',
'Released',
null
);
var dataoutput = nlapiSearchRecord(
'workorder',
null,
filter,
WOColumns
);
return dataoutput
}
Any help would be much appreciated as I'm new at this. If I do not include the Content-Type: application/json header, I receive "Invalid data format. You should return text."

The SS1 search results were funny beasts and did not used to serialize properly.
You should do something like:
function getWOSoftLock() {
var dataoutput = nlapiSearchRecord(
'workorder',
null,
new nlobjSearchFilter('status', null, 'is', 'Released'),
[
new nlobjSearchColumn('tranid'),
new nlobjSearchColumn('status')
]
);
if(!dataoutpout) {
nlapiLogExecution('AUDIT', 'No released work orders');
return [];
}
return dataoutput.map(function(res){
return {
tranid:res.getValue('tranid'),
status:res.getValue('status')
};
});
}
