AngularJS - Error: value.push is not a function

Question

I have a service defined like this ->

storegrServices.factory('productList', ['$resource', function($resource) {
    return $resource('', {},{
        query: {url:'/apis/productshome.php', method:'GET', isArray:false},
        getProductDetail: {url:'/apis/getproductdetail.php', method:'POST', isArray:true}
    });
}]);

And in the controller this is how I have called the POST ->

storegrControllers.controller('productPageCtrl', ['$scope','productList','$routeParams', function($scope, productList, $routeParams) {
    $scope.postVariable = new productList();
    $scope.postVariable.productcode =  $routeParams.code;
    $scope.postVariable.$getProductDetail();
}]);

This sends the product code to the server and the server returns with an array in the response. I have used isArray: true, however it still keeps giving me an error. I don't a 'value' variable/object in my code.

Please suggest how can I fix this.

This is the complete error that I get ->

This is the response from the server ->

Answer 1

I was able to work this around, answering it here so that it could benefit some one else too.

I modified my array response to be a json object like this and it worked.

{ "product":
[{"sno":21,"cat1":"Beverages","cat1code":"B","cat2":"Carbonated Drinks&Fruit Drinks","cat2code":"CDD","cat3":"Fruit Juices","cat3code":"FJ","cumulative":20,"brand":"Real Juice","product":"Apple","productcode":"B-CDD-FJ-1","imagename":"B-CDD-FJ-1","weight":200,"unit":0,"mrp":20,"margin":0,"wsp":0,"vat":0,"hbprice":0,"discount":0,"availableqty":0,"availableprice":0,"existingqty":0,"existingprice":0,"addedqty":0,"addedprice":0,"soldqty":0,"soldprice":0,"tags":"home"}]
}

Thank you.
