Servname not supported for ai_socktype

[PauletteASuare]

Description

I have make a simple Async producer. But i see this error happened:

dial tcp: lookup tcp/9092}: Servname not supported for ai_socktype

I change IP or Port to anything. no matter. Every time i see that error.

My simple producer.go is here:

package producer

import (
	"github.com/IBM/sarama"
	"log"
)

func NewAsyncProducer(brokers []string) (sarama.AsyncProducer, error) {
	config := sarama.NewConfig()
	//config.Producer.Return.Successes = true

	producer, err := sarama.NewAsyncProducer(brokers, config)
	if err != nil {
		return nil, err
	}

	// Create a goroutine to handle successful deliveries and errors asynchronously
	go func() {
		for {
			select {
			case success := <-producer.Successes():
				log.Println(success)
			case err := <-producer.Errors():
				log.Println(err)
			}
		}
	}()

	return producer, nil
}

Can you share what you're supplying as brokers value? It seems the bootstrap addresses are malformed in some way. They should be a string slice of hostname:port e.g.,

brokers := []string{
    "broker-0-example.com:9093",
    "broker-6-example.com:9093",
    "broker-3-example.com:9093",
    "broker-7-example.com:9093",
    "broker-5-example.com:9093",
    "broker-2-example.com:9093"
}
