   > could you provide the go code to test this issue?
   
   here is. I have wipe the sensitive info.
   
   ```go
   
   package main
   
   import (
   	"context"
   	"fmt"
   	"time"
   
   	"github.com/apache/pulsar-client-go/pulsar"
   )
   
   func main() {
   	url := ""
   	token := ""
   	topic := ""
   	subscName := ""
   
   	client, _ := pulsar.NewClient(pulsar.ClientOptions{
   		URL:               url,
   		Authentication:    pulsar.NewAuthenticationToken(token),
   		OperationTimeout:  30 * time.Second,
   		ConnectionTimeout: 30 * time.Second,
   	})
   
   	consumer, err := client.Subscribe(pulsar.ConsumerOptions{
   		Topic:            topic,
   		SubscriptionName: subscName,
   		Type:             pulsar.Shared,
   		RetryEnable:      true,
   		DLQ: &pulsar.DLQPolicy{
   			MaxDeliveries:    1,
   			RetryLetterTopic: topic + "-RETRY",
   			DeadLetterTopic:  topic + "-DLQ",
   		},
   	})
   	fmt.Printf("%s", err)
   
   	producer, _ := client.CreateProducer(pulsar.ProducerOptions{
   		Topic: topic,
   	})
   	snmid, _ := producer.Send(context.Background(), &pulsar.ProducerMessage{
   		Payload: []byte("hello"),
   	})
   	fmt.Printf("%x", snmid.Serialize())
   
   	ctx, cancel := context.WithTimeout(context.Background(), 10000*time.Millisecond)
   	defer cancel()
   	for {
   		msg, _ := consumer.Receive(ctx)
   		midOri := msg.ID()
   		midBytes := midOri.Serialize()
   		midNew, _ := pulsar.DeserializeMessageID(midBytes)
   		consumer.AckID(midNew)
   		// consumer.AckID(midOri)
   		// consumer.Ack(msg)
   		fmt.Printf("%s, ", msg.Payload())
   	}
   }
   ```
