Get structured data when using SubscribeSync

[pyprism]

From the doc I can see that nats.NewEncodedConn(nc, nats.JSON_ENCODER) is necessary. I tried to use this with SubscribeSync. But it's showing this method is not available.
Here is my code:

func RecieveMessageScrapper(subject string) {
	c := config.GetConfig()
	nc, _ := nats.Connect(c.GetString("nats_server"), nats.Token(c.GetString("nats_token")))
	defer nc.Close()
	
	// Subscribe
	sub, err := nc.SubscribeSync(subject)
	if err != nil {
		log.Fatal(err)
	}

	// Wait for a message
	msg, err := sub.NextMsg(44 * time.Minute)
	if err != nil {
		log.Fatal(err)
	}

	// Use the response
	log.Printf(string(msg.Data)) // printing [object object]
}

Now how can I parse this structured data ?

I'd recommend instead just calling json.Marshal and json.Unmarshal on the msg.Data field from the message struct instead of using the encoded connections. This also gives you access to msg.Respond method for example.

I also tried this way. Here is how I tried to parse in Go:

type replyMessage struct {
	content string `json:"content"`
}
var result replyMessage
	errr := json.Unmarshal(msg.Data, &result)
	if err != nil {
		log.Fatal(errr)
	}
	log.Println(result.content) // printing empty space
        log.Println(result)  // printing {}

And here is how I sending message from nodejs:

async function send(content, url) {
    let body = {'content': content};

    const sc = StringCodec();
    let json = JSON.parse(await readFile("config.local.json", "utf8"));
    const nc = await connect({'servers': json['nats_server'], 'token': json['nats_token']});

    nc.publish(url, sc.encode(body));
}

Somehow It can't parse the expected value.
