Why does HotelSearch return an ERR.NGHP-DISTRIBUTION.INTERNAL_ERROR? - sabre

Question

I am trying to use the HotelSearch REST api. I have tested it on the Dev Studio website by Sabre and while it is slow to respond it works on a Chrome browser. I then tried to get his working in the sample app Rest2SG Sabre provide, as well as Postman. However it returns this error on both platforms:
Here is the method I have added to the sample app:
private void getHotelSearch()
{
Job job = new Job("Getting HotelSearch")
{
#Override
protected IStatus run(IProgressMonitor monitor)
{
setText("Waiting for response...");
toggleAllButtons(false);
try
{
Rest2SgRequest request =
lockId > 0 ? new Rest2SgRequest(lockId) : new Rest2SgRequest();
// for the list of available service action names
// please refer to REST documentation
// this same as action in redapp.xml authorization
request.setUrl("/v2.0.0/hotel/search");
//request.setHeaders(getContentDescription())
// previously generated document, normally developer will
// have to prepare one by himself
String payload = getRequestBody("sample.json"); // we
// preload
request.setPayload(payload);
request.setHttpMethod(HTTPMethod.POST);
request.setContentType("application/json");
request.setAuthTokenType(AuthTokenType.SESSIONLESS);
Rest2SgServiceClient client = new Rest2SgServiceClient(COM);
ClientResponse <Rest2SgResponse> rsp = client.send(request);
LOGGER.info("Rest2Sg request processing success: " + rsp.isSuccess());
if (rsp.isSuccess())
{
// check if processing ended in with success
Rest2SgResponse response = rsp.getPayload();
String responseBody = response.getResponseBody();
response.getResponseCode();
response.getResponseHeaders();
setText(responseBody);
}
else
{
printErrors(rsp.getErrors());
System.out.println(rsp.getErrors().toString());
}
}
catch (Exception e)
{
e.printStackTrace();
}
toggleAllButtons(true);
return Status.OK_STATUS;
}
};
job.schedule();
}
Here is the sample JSON:
{
"HotelSearchRQ": {
"POS": {
"Source": {
"PseudoCityCode": "43X5"
}
},
"SearchCriteria": {
"MaxResults": 20,
"SortBy": "DistanceFrom",
"SortOrder": "ASC",
"TierLabels": false,
"GeoSearch": {
"GeoRef": {
"Radius": 2,
"UOM": "MI",
"RefPoint": {
"Value": "DFW",
"ValueContext": "CODE",
"RefPointType": "6",
"StateProv": "TX",
"CountryCode": "US"
}
}
}
}
}
}
Does anyone know why I am getting the error below?
[Error [code=400, description={"errorCode":"ERR.NGHP-DISTRIBUTION.INTERNAL_ERROR","message":"Error occurred while invoking service restish:convertToOutputFormat:1.71.3","status":"Incomplete","type":"Application","timeStamp":"2022-06-20T21:00:51-05"}, type=HTTP]]
As I mentioned this JSON works on their website.

This problem is caused by missing header information. The following line needs to be added to the request:
request.setHeaders("{\"Accept\": \"application/json\"}");
