Gloud-Java. PERMISSION_DENIED: Google Cloud Pub / Sub-API (experimentell)

Ich benutze die experimentelle Bibliothek von gloud-java. Nach dem heutigen Update ist ein Fehler aufgetreten. Beispiel aus lokaler Bibliothek ausführen (Dieser Fehler wird automatisch in der Google Cloud Flexible Engine angezeigt, obwohl die Bereitstellung eine Woche lang nicht erfolgt ist.)

public class PullTest {
private static final transient Logger logger = Logger.getLogger(MethodHandles.lookup().lookupClass().getName());

public static void main(String... args) throws Exception {
    try (PubSub pubsub = PubSubOptions.defaultInstance().service()) {
        String subscriptionName = "subscription-segment";
        Subscription subscription = pubsub.getSubscription(subscriptionName);
    }
}
}

Ausnahme auslösen

Wie kann man dieses Problem umgehen? Das Problem entstand aus dem Nichts. Am Morgen hat es geklappt:)

p.s.

$ gcloud info

zeigt die richtigen Informationen

$ gcloud auth login
