Can't return *amqp.Channel from a function when using the Go RabbitMQ streadway/amqp driver

I'm trying to connect to a RabbitMQ bus using the streadway/amqp driver for Go. I'm working on a reconnection routine and, for it, I have a rabbitMQConsume function call a rabbitMQConnect function.

func rabbitMQConnect(cfg objects.GlobalConfig) (*amqp.Connection, *amqp.Channel, error) {
	rabbitConfig := amqp.Config{
		Vhost:     cfg.RabbitVHost,
		Heartbeat: 5,
	}

	//Open connection to Rabbit
	url := fmt.Sprintf("amqp://" + cfg.RabbitUser + ":" + cfg.RabbitPassword + "@" + cfg.RabbitHost + ":" + cfg.RabbitPort + cfg.RabbitVHost)

	conn, err := amqp.DialConfig(url, rabbitConfig)
	if err == nil {
		return nil, nil, err
	}

	ch, err := conn.Channel()
	if err != nil {
		return nil, nil, err
	}
	// Create Exchange if it doesn't exist
	err = ch.ExchangeDeclare(
		"ali",    // name
		"direct", // type
		true,     // durable
		false,    // auto-deleted
		false,    // internal
		false,    // no-wait
		nil,      // arguments
	)
	if err != nil {
		return nil, nil, err
	}

	//Declare queue
	_, err = ch.QueueDeclare(
		cfg.RabbitQueue, // name
		true,            // durable
		false,           // delete when usused
		false,           // exclusive
		false,           // no-wait
		nil,             // arguments
	)
	if err != nil {
		return nil, nil, err
	}

	//Bind queue
	err = ch.QueueBind(
		cfg.RabbitQueue,    // queue name
		cfg.RabbitKey,      // routing key
		cfg.RabbitExchange, // exchange
		false,
		nil,
	)
	if err != nil {
		return nil, nil, err
	}
	return conn, ch, nil
}

//RabbitMQConsume setup the channel/exchange data
func rabbitMQConsume(cfg objects.GlobalConfig) (*amqp.Connection, <-chan amqp.Delivery, error) {
	conn, ch, err := rabbitMQConnect(cfg)
	if err != nil {
		return nil, nil, err
	}

	consumerID, err := helper.GetConsumerID()
	if err != nil {
		return nil, nil, err
	}

	//Start receiving data in the msgs channel
	msgs, err := ch.Consume(
		cfg.RabbitQueue, // queue
		consumerID,      // consumer
		false,           // auto-ack
		false,           // exclusive
		false,           // no-local
		false,           // no-wait
		nil,             // args
	)
	if err != nil {
		return nil, nil, err
	}

	return conn, msgs, nil
}

The problem I'm having is that the value of ch and conn when they're returned to rabbitMQConsume from rabbitMQconnect, are nil and the program panics when I run the ch.Consume line.
I'm losely basing this on this example
Any ideas? Thanks!

You have a typo in your error checking after amqp.DialConfig !

Change the err == nil to err != nil

conn, err := amqp.DialConfig(url, rabbitConfig)
if err != nil { // you typed it as err == nil
    return nil, nil, err
}
