Issue connecting pub/sub from PCF

I'm trying to connect google Pub/Sub from PCF environment(Spring boot app). The app is successfully loaded the credentials from credentials.json file and it printed Project ID. but it is printing below error after started.

c.g.a.oauth2.ComputeEngineCredentials : Failed to detect whether we are running on Google Compute Engine. ERROR 13 --- [nio-8080-exec-4] o.a.c.c.C.[.[.[/].[dispatcherServlet] : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.IllegalStateException: Expected the service InnerService [FAILED] to be RUNNING, but the service has FAILED] with root cause java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.

Here is the code which I'm using and I'm invoking this method from a sample rest controller.

public static void subscribeAsyncExample(String projectId, String subscriptionId) {
ProjectSubscriptionName subscriptionName =
    ProjectSubscriptionName.of(projectId, subscriptionId);
System.out.println("Processing messages...");
MessageReceiver receiver =
    (message, consumer) -> {
      System.out.println("Id : " + message.getMessageId());
      System.out.println("Data : " + message.getData().toStringUtf8());
      consumer.ack();
    };
Subscriber subscriber = null;
try {
  subscriber = Subscriber.newBuilder(subscriptionName, receiver).build();
  subscriber.startAsync().awaitRunning();
  subscriber.awaitTerminated();
} finally {
  if (subscriber != null) {
    subscriber.stopAsync();
  }
}

}
