@BalaDhruv This error occurs when you pass invalid parameter in below function. check it first.

const web_socket = new WebSocketV2({
jwttoken: 'YOUR_JWT_TOKEN_HERE',
apikey: 'YOUR_API_KEY_HERE',
clientcode: 'YOUR_CLIENT_ID_HERE',
feedtype: 'YOUR_FEED_TOKEN_HERE',
});

@nitish-bane I tried this code and i got this error

Code:

let { WebSocketV2 } = require('smartapi-javascript');
var axios = require('axios');

const speakeasy = require('speakeasy');
const secretKey = '';

// Generate TOTP code
const totpCode = speakeasy.totp({
secret: secretKey,
encoding: 'base32',
});

var axios = require('axios');
var data = JSON.stringify({
"clientcode":"K55544670",
"password":"3123",
"totp":${totpCode}
});

var config = {
method: 'post',
url: 'https://apiconnect.angelbroking.com//rest/auth/angelbroking/user/v1/loginByPassword',

},
data : data
};

axios(config)
.then(function (response) {
let a=response.data;
console.log(a.data.feedToken+"\n\n\n")

console.log(a.data.jwtToken);
const jwt=a.data.jwtToken

let web_socket = new WebSocketV2({
    jwttoken: jwt, // replace this with your own credentials
    apikey: 'hjdhdhdg',
    clientcode: 'K55544670',
    feedtype: 'order_feed',
});
web_socket.connect().then((res) => {
    let json_req = {
        correlationID: 'abcde12345',
        action: 1,
        mode: 2,
        exchangeType: 1,
        tokens: ["99926009", "99926000"]// token for nifty and bank nifty
    };

    web_socket.fetchData(json_req);
    web_socket.on('tick', receiveTick);
    function receiveTick(data) { // your code to process tick data
    }
}
)

})
.catch(function (error) {
console.log(error);
});
