I have copied the code from the book in a Playground, exactly like so:

```auto
func story(id: Int) -> AnyPublisher<Story, Error> {
    URLSession.shared.dataTaskPublisher(for: EndPoint.story(id).url)
      .receive(on: apiQueue)
      .map(\.data)
      .decode(type: Story.self, decoder: decoder)
      .catch { _ in Empty<Story, Error>() }
      .eraseToAnyPublisher()
  }

```

However, when I call the method, the debugger prints `keyPath2()` for the completion rather than `finished`. What am I doing wrong?

```auto
api.story(id: 1000)
  .receive(on: DispatchQueue.main)
  .sink(receiveCompletion: { print($0) }, receiveValue: { print($0) })
  .store(in: &subscriptions)

```

Output:

```auto
