uiSref not working in an angular component

[vzorge]

Hello,

I am not sure if I should ask this here on on the angular repository. But since I am using angular-hybrid I will ask it here.

The following line in the construction of UIsref is throwing an error for me: this._statesSub = _router.globals.states$.subscribe(function () { return _this.update(); });

I have tried to trace this in the code. What I found was a bit confusing, which is why I am posting this question.

When I debug, I see that the router.globals is defined as follows: globals: {, $current: {..}, $get: {...}, current: {..}, lastStatedTransitionId: 0, params: {...}, successfulTransitions: {...}, transition: null, transitionHistory: {...}

When I look at the source, this matches UIRouterGlobals from @angular-ui/core perfectly. So I was wondering why it was even assumed there would be a states$ variable on here. I did find where it comes from, the interface in @uirouter/core/lib/globals of ui-router/rx.

I don't quite have the knowledge to know what I did wrong here. I can post my whole setup, but if someone can help me understand how those globals.states$ is supposed to be set, I can try to figure out a minimal reproduction.

Edit: Ok, right after I typed this I found a solution. If I add the following to me bootstrapping, it no longer throws the error: uiRouter.plugin(UIRouterRx);

Not sure why this is mandatory and if it is, why it is not listed in the Readme. Therefor leaving this issue open for now.
