Querying relations in loopback doesn't work via Angular SDK

I am trying to query a model relation I have two models 1. Workers 2. Skills

Worker hasMany Skills

I can query the api via the explorer http://localhost:3000/explorer/#!/Workers/prototype_get_skills and /api/Worker/:id/Skills url and it gives back a list of skills for a give Worker Id

The issue happens when i try to call the Worker.skills() method generated by Angular SDK where i get a 404 Not Found Error

Below is the Angular implementation that i have

 angular.module('worker-dashboard').factory('WorkerDashboardSkillService',['Worker',
    function(Worker){
        function getWorkerSkills(worker){
            return  Worker.skills({
                    filter:
                    {
                        where:
                        {
                            "workerId" : worker
                        }
                    }
                },function(data){
                    console.log(data);
                },
                function(err){
                    console.log(err);
                })
        }
        function addWorkerSkills(worker,skill){
            return  Worker.skills.create(
                {
                    "skillName": skill.name,
                    //TODO chabge below
                    "skillCategory": skill.name,
                    "workerId": worker
                },function(data){
                    console.log(data);
                },
                function(err){
                    console.log(err);
                })
        }

        return{
            getWorkerSkills : getWorkerSkills,
            addWorkerSkills : addWorkerSkills
        }
    }]);

I also tried an example loopback-getting-started-intermediate

Which has an example

$scope.reviews = Review.find({
filter: {
where: {
publisherId: $rootScope.currentUser.id
},
include: [
'coffeeShop',
'reviewer'
]
}
});

However this example is looks like for the belongsTo relation and when i tried modifying it couldn't do it
