   > 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,
        })
   
        producer, _ := client.CreateProducer(pulsar.ProducerOptions{
                Topic: topic,
        })
        snmid, _ := producer.Send(context.Background(), &pulsar.ProducerMessage{
                Payload: []byte("hello"),
        })
        fmt.Printf("%x", snmid.Serialize())
   
        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)
        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())
        }
   }
