Unexpected token , in Angular code after $http request - angularjs

Question

I am submitting an $http request to my server using this code below, yet all the of sudden Angular is complaining about an "Unexpected token , " somewhere.
function sendAggrRequestToServer(url) {
var deferred = $q.defer();
$http({
method: 'GET',
encoding: 'JSON',
headers: {
'Access-Control-Allow-Origin': 'true'
},
withCredentials: true,
url: url
}).success(function (data, status, headers, config) {
var retval = data;
deferred.resolve(retval);
}).error(function (data, status, headers, config) {
logErr("Error submitting aggregation request to server: " + status);
});
return deferred.promise;
}
The strange thing is that this exact URL works successfully both in the browser and in Fiddler. And the Json data is returned as expected. However, for some strange reason my javascript code is throwing this
exception:
[app] [HT Error] Unexpected token ,
Object {exception: SyntaxError, cause: undefined}
angular.js:9778
(anonymous function) angular.js:9778
logIt logger.js:55
logError logger.js:49

Scope.$digest angular.js:12224
Scope.$apply angular.js:12516
done angular.js:8204
completeRequest angular.js:8412
xhr.onreadystatechange
And my URL is :
http://localhost:49479/api/aggr?sid=9630a8040ee6c901a4034c07894abc317272f855c757a4c60a6a&kri=[CDSStress%20A]:[USD%2010Y%20X%20-1.25],[CDSStress%20A]:[USD%2010Y%20X%201.25]&aggrFunc=SUM([CDSStress%20A]:[USD%2010Y%20X%20-1.25]),SUM([CDSStress%20A]:[USD%2010Y%20X%201.25])&dim=Counterparty
FYI: All appears to be fine in angular.js at this point in angular, and I can indeed see the response data (which is definitely valid Json data). The callback status param has a value of "200" and the statusText is 'OK':
function completeRequest(callback, status, response, headersString, statusText) {
// cancel timeout and subsequent timeout promise resolution
timeoutId && $browserDefer.cancel(timeoutId);
jsonpDone = xhr = null;
// fix status code when it is 0 (0 status is undocumented).
// Occurs when accessing file resources or on Android 4.1 stock browser
// while retrieving files from application cache.
if (status === 0) {
status = response ? 200 : urlResolve(url).protocol == 'file' ? 404 : 0;
}
// normalize IE bug (http://bugs.jquery.com/ticket/1450)
status = status === 1223 ? 204 : status;
statusText = statusText || '';
callback(status, response, headersString, statusText);
$browser.$$completeOutstandingRequest(noop);
}
};
Here is a screen image of the break point where I can inspect the "response" param:
However, as soon as it resolves the promise and returns to my calling function, angular throws the Unexpected token error.
I have been using this for days now, but today I must have introduced something to cause this. I just can't figure out what !
Your advice and guidance is greatly appreciated.
regards.

UPDATE:
I now find Angular throwing the actual exception inside $HttpProvider() on this line :
data = fromJson(data);
inside here :
function $HttpProvider() {
var JSON_START = /^\s*(\[|\{[^\{])/,
JSON_END = /[\}\]]\s*$/,
PROTECTION_PREFIX = /^\)\]\}',?\n/,
CONTENT_TYPE_APPLICATION_JSON = {'Content-Type': 'application/json;charset=utf-8'};
var defaults = this.defaults = {
// transform incoming response data
transformResponse: [function(data) {
if (isString(data)) {
// strip json vulnerability protection prefix
data = data.replace(PROTECTION_PREFIX, '');
if (JSON_START.test(data) && JSON_END.test(data))
data = fromJson(data);
}
return data;
}],
// transform outgoing request data
transformRequest: [function(d) {
return isObject(d) && !isFile(d) && !isBlob(d) ? toJson(d) : d;
}],
// default headers
headers: {
common: {
'Accept': 'application/json, text/plain, */*'
},
post: copy(CONTENT_TYPE_APPLICATION_JSON),
put: copy(CONTENT_TYPE_APPLICATION_JSON),
patch: copy(CONTENT_TYPE_APPLICATION_JSON)
},
xsrfCookieName: 'XSRF-TOKEN',
xsrfHeaderName: 'X-XSRF-TOKEN'
};
And sendAggregationREquest() is called from here :
function buildAndSendAggregationQuery() {
// iterate list in reportsContext , pass data to to sendAggregationRequest()
var userKRIs = vm.kriUserDataSource.get();
userKRIs.load();
var group;
var kri = '';
var aggrFunc = '';
var aggrKriFuncArray;
var dimension = vm.selectedDimen;
var dimenMulti = '';
var applyScenarioAggr = false;
if (vm.kriUserDataSource.data()[0].group == '99_HSVaR') {
applyScenarioAggr = true;
}
// Call function to build the aggr function. Return value is an array.
if (applyScenarioAggr) {
aggrKriFuncArray = reportsContext.buildAggrFunc(vm.kriUserDataSource.data(), 'AVERAGE');
}
else {
aggrKriFuncArray = reportsContext.buildAggrFunc(vm.kriUserDataSource.data(), 'SUM');
}
kri = aggrKriFuncArray[0];
aggrFunc = aggrKriFuncArray[1];
for (var i = 0; i < vm.multiSelectedDimen.length; i++) {
dimenMulti += vm.multiSelectedDimen[i] + ',';
}
dimenMulti = dimenMulti.substr(0, dimenMulti.length - 1); // ' remove final ","
sendAggregationRequest(kri, aggrFunc, dimension); //dimenMulti);
}
and finally, the response data that comes back from server prior to that exception:
{"status":"SUCCESS", "messages":[], "data":[{"attributes":[{"name":"Counterparty","type":"string"},{"name":"SUM(CDSStress A:USD 10Y X -1.25)","type":"double"},{"name":"SUM(CDSStress A:USD 10Y X 1.25)","type":"double"}],"rows":[{"id":0,"values":["Goldman",0.,0.]},{"id":1,"values":["IBM",0.,0.]},{"id":2,"values":["JP Chase",0.,0.]},{"id":3,"values":["MINESCONDIDA",0.,0.]},{"id":4,"values":["Merrill",0.,0.]},{"id":5,"values":["Nokia",0.,0.]},{"id":6,"values":["Pequot",0.,0.]},{"id":7,"values":["Pimco Fund A",0.,0.]},{"id":8,"values":["Pimco Fund B",0.,0.]},{"id":9,"values":["Deutsche",0.,0.]},{"id":10,"values":["Ditech",0.,0.]},{"id":11,"values":["GM Isuzu",0.,0.]},{"id":12,"values":["GM Opel",0.,0.]},{"id":13,"values":["GMAC",0.,0.]},{"id":14,"values":["GMAC Insurance",0.,0.]},{"id":15,"values":["GSAM",0.,0.]},{"id":16,"values":["General Insurance",0.,0.]},{"id":17,"values":["Genworth",0.,0.]},{"id":18,"values":["AIG",0.,0.]},{"id":19,"values":["Andor",0.,0.]},{"id":20,"values":["BARCLAYS",92.7731197209214,-10.1717767200607]},{"id":21,"values":["BHHSH",0.,0.]},{"id":22,"values":["BHPBFIN",0.,0.]},{"id":23,"values":["BHPSTEEUR",1468.80370935,-161.395632863801]},{"id":24,"values":["BHPSUS",0.,0.]},{"id":25,"values":["BLUESCOPEFIN",0.,0.]},{"id":26,"values":["CSFB",3.35029024626419,-0.367366071961442]},{"id":27,"values":["BLOSOFL",0.,0.]},{"id":28,"values":["GRMOBND",0.,0.]}]}]}

Answer 1

can you make a jsfiddle ? or at least show us how you call the sendAggrRequestToServer method.
It shouldbe
var promise = sendAggrRequestToServer(url);
promise.then(function(data) {
console.log('Success we got: ' + data);
}, function(reason) {
console.log('Failed we got: ' + reason);
}, function(update) {
console.log('Strange we got: ' + update);
});
Thx
