角度资源-$ resource：badcfg

Question

My angular throws me

Error: [$resource:badcfg] Error in resource configuration for action query . Expected response to contain an array but got an object

I have no idea why this happens. I have a db with schools, and each schools has a city property. i'm trying to get all the schools in a given city. On the server, my controller has a function which is supposed to do exactly that:

getSchoolByData: function(req, res, next) {
    School.find({city: req.params.reqCity}).exec(function (err, collection) {
        if (err) {
            console.log("Could not load desired school: " + err);
        }
        res.send(collection);

    });
}

On my client side I have a resource and another controller: resource:

app.factory('SearchSchoolResource', function($resource) {
    var SearchSchoolResource = $resource('/schoolSearchResult/:reqCity', {city: 'reqCity'}, { update: {method: 'PUT', isArray: false}});
    return SearchSchoolResource;
}); 

controller:

app.controller('SearchSchoolCtrl', function($scope, $routeParams, SearchSchoolResource) {
    $scope.schools = SearchSchoolResource.query({city: $routeParams.reqCity});
});

I have no idea which one of these fails to work properly and I have no idea how to check. I'm new to angular and node, and I spent over 72 hours on this, so if someone can tell me how to fix this, it will be amazing! Other than that I managed to return all the schools, and a single school based on given id just fine, but returning schools based on city fails.

EDIT:

If I just put the name of the city in the find function like

... find({city: 'name'}) ...

It works, but if I use req.params.reqCity it doesn't. I can't figure out why it doesn't work, it seems like req.params.reqCity is returning something different and not the given city name. Tried just using .ToArray instead of .exec and it doesn't work again. Can't figure out what the req.params.reqCity returns and still can't figure out how to fix this.

Try this way, it should work. In addition to get i am also adding other operation's syntax.

Service:

 app.factory('SchoolService',function($resource){
            return $resource('/schoolSearchResult/:reqCity', 
            {
                reqCity: '@reqCity'
            },
            {
                'update': { method:'PUT' }
            },
            {
                'get': { method: 'GET', isArray: false }
            },
            {
                'delete': { method: 'DELETE'}
            }
        );
        });

controller:

app.controller('SearchSchoolCtrl', function($scope, $routeParams, SchoolService) {
        var schoolService = new SchoolService();
        schoolService.$get({reqCity : $routeParams.reqCity},function(result){
                    $scope.schools = result;
                });
    });
