why am I getting "actor not found" when calling the last succesful run from an actor in Apify?

I'm getting this error when calling last succesful run from an Apify actor. Does anybody know why? I couldn't find the actor id anywhere so I used the name of the actor instead.

this is my api call to get last succesful fun from my actor.....................................

func getZillowListings() -> Bool {
