I am trying to implement websocket 2.0 in node SDK,
but it shows "Error while processing message"
can you please help me, what i am doing wrong in my code

const feed = {

        "correlationID": "abcde12345",

        "action": 1,

        "params": {

             "mode": 1,

             "tokenList": [

                  {

                       "exchangeType": 2,

                       "tokens": [

                            "55429"

                       ]

                  }

             ]

        }

   } new WebSocketClient({
    clientcode: process.env.CLIENT_CODE,
    jwttoken: session.get("access_token"),
    apikey: process.env.API_KEY,
    feedtype: JSON.stringify(feed)
});


ws2.connect()
    .then(() => {
        ws2.fetchData("subscribe",JSON.stringify(feed));  // ACTION_TYPE: subscribe | unsubscribe FEED_TYPE: order_feed
        setTimeout(function () {
            ws2.close()
        }, 60000)
    })
    
ws2.on('tick', receiveTick);

function receiveTick(data) {
    console.log("receiveTick:::::", data);
}
