Have you confirmed that this works - at least that the apps.get_instances call responds properly under normal conditions?

@Enkidu93 Yes, I stepped through it both when an e2e test was running (and so using the autoscaler), and when no e2e test was running (and so there were no workers for the autoscaler).
