Ngrx Store not receiving cached response from Observable from interceptor

Location: effects.ts file on fetchCards and fecthLectures actions Description: The interceptor creates an Observable from the cached response, but the the response is not passed on in the service, nor in the effects pipe chain Expected behaviour: effect makes a call to the service, which will load the cards from the server. This call is intercepted by the http interceptor which will look up if there is a cached response. If there is one it will return an observable of the response and not make an http call to the server. The observable is returned by the service and the store gets the response and updates its data Steps to reproduce: Go to a lecture. Refresh the page. The cards will be undefined

It seems like the issue happends only if the component has not yet been initialized. The behaviour can be observed when doing the following:

• delete the lectures from localstorage
• refresh (here cards will be loaded from server)
• navigate to a route and then navigating back home using the button in the navlist. The lectures are now correctly loaded from cache. However when refreshing the page it does not work
