Below is my code where i'm trying to subscribe using subscriber name.

@SpringBootApplication
@EnableScheduling
@EnableCaching
public class CodenameHere {

    @Autowired
    PubSubTemplate pubSubTemplate;

    public static void main(String[] args) {
        SpringApplication.run(CodenameHere.class, args);
    }

    @Bean
    public MessageChannel inputMessageChannel() {
        return new PublishSubscribeChannel();
    }

    @Bean
    public PubSubInboundChannelAdapter inboundChannelAdapter(
        @Qualifier("inputMessageChannel") MessageChannel messageChannel,
        PubSubTemplate pubSubTemplate) {
        PubSubInboundChannelAdapter adapter =
            new PubSubInboundChannelAdapter(pubSubTemplate, "pullSubscriber");
        adapter.setOutputChannel(messageChannel);
        adapter.setAckMode(AckMode.MANUAL);
        adapter.setPayloadType(String.class);
        return adapter;
    }

    // Define what happens to the messages arriving in the message channel.
    @ServiceActivator(inputChannel = "inputMessageChannel")
    public void messageReceiver(
        String payload,
        @Header(GcpPubSubHeaders.ORIGINAL_MESSAGE) BasicAcknowledgeablePubsubMessage message) {
        System.out.println("Message arrived via an inbound channel adapter from pullSubscriber! Payload: " + payload);
        message.ack();
    }
}

Below is my application.properties

spring.cloud.gcp.core.enabled=true
spring.cloud.gcp.project-id=my-project

spring.cloud.gcp.pubsub.enabled=true
spring.cloud.gcp.pubsub.project-id=my-project
spring.cloud.gcp.pubsub.emulator-host=localhost:8085

I've started the emulator and created the topic and subscription and able to publish and subscribe using the same topic and subscriber name on python-pubsub sample (https://github.com/googleapis/python-pubsub).

I wonder what i'm missing?
