Angular state resolve not injecting into controller

On the documentation (https://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$stateProvider) the specification of the method mentions the following:

The map object is:

key - {string}: name of dependency to be injected into controller factory - {string|function}: If string then it is alias for service. Otherwise if function, it is injected and return value it treated as dependency. If result is a promise, it is resolved before its value is injected into controller.

with the following as an example:

resolve: {
    myResolve1:
        function($http, $stateParams) {
          return $http.get("/api/foos/"+stateParams.fooID);
        }
    }

So I suggest you change your code into one of these options to make it as simple a possible and, using chrome developer tool, place a breakpoint on the first line on the method:

resolve: {
    portalsForUser: ['userPortalService', '$stateParams', function (userPortalService, $stateParams) {
        var userId = $stateParams.id; //place your breakpoint here
        return userPortalService.getPortalsForUserPromise(userId);
    }] 
}

Check what is going on with $stateParams; it is not impossible that, for some reason, at this moment, everything is not initialized yet because values don't come from the url, therefore, the id property is undefined. Try to inject "$state" and see if $state.params.id contains what you expect instead. (like mentioned in here: https://angular-ui.github.io/ui-router/site/#/api/ui.router.state.$state). Here is what it could look like:

resolve: {
    portalsForUser: ['userPortalService', '$state', function (userPortalService, $state) {
        var userId = $state.params.id; //place your breakpoint here
        return userPortalService.getPortalsForUserPromise(userId);
    }] 
}

Hope that if it doesn't solve your problem, at least it will help you to find it.

EDIT:

It seems all the previous doesn't go to the right direction.

Here is my new direction: I used your plunker to create a hosted site on my computer (using http-server: https://www.npmjs.com/package/http-server). My version that doesn't seem to be very different than yours works perfectly. Here is the full code:

app.js:

(function () {
    'use strict';

    var myApp = angular.module("myApp", ["ui.router"]);

    myApp
        .config(config)
        .controller("portalsForUserCtrl", portalsForUserCtrl)
        .service('userPortalService', userPortalService)
        .controller("mainCtrl", mainCtrl)

    mainCtrl.$inject = ["userPortalService", "$state"];

    function mainCtrl(userPortalService, $state) {
        var vm = this;

        vm.clickMe = function () {
          var userId = 1;
            $state.go("portalsForUser", { "id": userId });
        }
    };

    config.$inject=["$stateProvider"];

    function config($stateProvider) {
            $stateProvider
                // PortalsForUser GET
                .state("portalsForUser", {
                    url: "/userPortal/portalsForUser/:id",
                    templateUrl: "portalsForUser.html",
                    controller: "portalsForUserCtrl as vm",
                    resolve: {
                        portalsForUser: ['userPortalService', '$stateParams', function (userPortalService, $stateParams) {
                            return userPortalService.getPortalsForUserPromise($stateParams.id).then(function(response){return response.data;});
                        }]
                    }
                })
        }

    userPortalService.$inject = ['$http', '$q', '$timeout']

    function userPortalService($http, $q, $timeout) {
        var getPortalsForUserPromise = function (id) {
            var myId=id;
            var deferred=$q.defer();

            $timeout(function(){
                deferred.resolve({data:[
                    {
                    id: 16,
                    portal: {
                        portalName: "Portal1-" + myId,
                        portalId: 1
                    }
                    },
                    {
                    id: 17,
                    portal: {
                        portalName: "Portal2-" + myId,
                        portalId: 2
                    }
                    }
                ]});
            },5000);
            return deferred.promise;
        };

        return {
            getPortalsForUserPromise: getPortalsForUserPromise
        };
    };

    portalsForUserCtrl.$inject = ['portalsForUser', 'userPortalService'];

    function portalsForUserCtrl(portalsForUser, userPortalService) {
        console.log("in portalsForUserCtrl");
        var vm = this;
        vm.portalsForUser = portalsForUser;
        console.log(portalsForUser);
    };
}());

I added the div ui-view in index.html like suggested by somebody else, but I believe this was already in your initial project. I also tried to simulate the service like the real one would work (with a promise and with a property data).

Are you sure you have correct versions of ui-router and angular?
