Injection doesn't work in Typescript

Question

I'm doing a web app with Angular 1 using Typescript. I have to create a Factory in which I have some conditions in which I want to inject some dependences. This is the code:

.factory('myFactory', function ($q: angular.IQService, $location: ng.ILocationService, $localStorage: any, Ob: any, $injector: ng.auto.IInjectorService) {
        return {
        f: function (config: any) {
            config.headers = config.headers || {};
            if (Ob.auth) {
                let $state = $injector.get("$state");
                $state.go("app.auth");
            }
            return config;
        },
   .... other methods....
        };
})

When I compile I have this error in console:

ts\inj.ts(110,14): error TS2339: Property 'go' does not exist on type '{}'.
ts\inj.ts(126,13): error TS2339: Property 'go' does not exist on type '{}'.
[10:46:55] TypeScript: 2 semantic errors
[10:46:55] TypeScript: emit succeeded (with errors)

How can I solve it?

Answer 1

Looking at this page it doesn't look like the $state object has a go() method, which is why TypeScript is throwing an error. Did you mean to use $state.get() instead?
