带有查询参数的节点js-app.get方法-内部服务器错误

Controller.js

  function _loadMoreItems() {
                    console.log("load more items");                
                    var paginate = {
                        page : $scope.page,
                        perPage : $scope.perPage
                    };
                  ItemService.loadItems(paginate).then(function(result){
                        console.log("pagination done");
                        console.log("result");
                        console.log(result);
                        console.log("result length");
                        console.log(result.length);
                        for(var i=0;i<result.length;i++){
                            $scope.itemList.push(result[i]);
                        }
                        $scope.page = $scope.page + 1;
                    },function(err){
                        console.log("error");
                        console.log(err);
                    });
                }

Service.js-ItemService

angular.module("myapp.item")
    .factory("myapp.item.service", ['Restangular',
        function(Restangular) {
            var restAngular = Restangular.withConfig(function(Configurer) {
                Configurer.setBaseUrl('/api/item');
            });
            return {
                create: restAngular.all('')
                    .post,
                loadItems: function(paginate) {
                    return restAngular.all('query').getList(paginate);
                }
            }
        }
    ]); 
   Here I pass the paginate object as query param.

下面是我在nodejs中的路由

ApiRouter.get('/query',auth.requiresLogin, ApiCtrl.load);

下面是我的node-js方法来处理get

exports.load = function(req, res) {
    console.log("req query");
    console.log(req.query);
    var myList=[];
     return res.status(200)
                .send(myList);
};

我得到以下错误。

http://localhost:3000/api/item/query?page=0&perPage=3  500 (Internal Server Error)

我得到内部服务器错误没有任何原因。如果我将路由器中的"getList"更改为"post（paginate）"，则不会出现此错误。有些地方我错过了为getList写东西。请告诉我哪里错了。

谢谢。
