Hi @Turbo87 👋

I am in the process of upgrading from ember-test-selectors@5 to ember-test-selectors@6.

One of our tests breakes with ember-test-selectors@6 with the error

router_js.js:1194 Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'shouldSupersede')
    at NamedTransitionIntent.applyToHandlers (router_js.js:1194:1)
    at NamedTransitionIntent.applyToState (router_js.js:1137:1)
    at PrivateRouter.applyIntent (router_js.js:2148:1)
    at calculatePostTransitionState (router.js:1389:1)
    at Router._prepareQueryParams (router.js:868:1)
    at RouterState.isActiveIntent (router_state.js:26:1)
    at RoutingService.isActiveForRoute (routing.js:101:1)
    at LinkTo.isActiveForState (index.js:8187:1)
    at LinkTo.get isActive [as isActive] (index.js:8102:1)
    at LinkTo.get class (index.js:7962:1)

The error happens when clicking this LinkTo 👇

<LinkTo @route={{this.router.currentRouteName}} @query={{hash tab="dummy"}}>Click me</LinkTo>

If I remove the @query argument, no more error:

<LinkTo @route={{this.router.currentRouteName}}>Click me</LinkTo>

I should also add that the error only happens when I render the route with the LinkTo from its URL. If I transition to this route, and then click the LinkTo, no error…

You opened this emberjs/ember.js ticket, emberjs/ember.js#20051, with the same error, but the call stack is not exactly the same, and our codebase uses ember-source 3.28, not 4.3 like your ticket mentions…

You seem to have a better understanding of all this code than I do. Do you have any idea why this worked under ember-test-selectors@5, but not with ember-test-selectors@6, and what I could do to fix it?

Thanks a lot for your help!

unfortunately I have no clue why that would be the case. on first glance it seems unlikely that test-selectors would be able to cause this in any way since we don't interfere with routing at all 🤔
