Unable to recieve to tick data

[tushar]

Always receiving this -

Receive stock ticks:: [ { ak: 'nk', task: 'cn', msg: 'cn' } ]
Receive stock ticks:: [ { ak: 'nk', task: 'mw', msg: 'mw' } ]

I'm using my client_code, password, and Key.

Below is the code, I've passed my client details (code below doesn't contain my details)

Code

let { SmartAPI, WebSocket } = require("smartapi-javascript");

let smart_api = new SmartAPI({
    api_key: "KEY",    // PROVIDE YOUR API KEY HERE
 });


smart_api.generateSession("client_code", "PWD")
    .then((data) => {
        // console.log(data)
        return data;
    })
    .then((data) => {
        console.log(data)
        let web_socket = new WebSocket({
            client_code: "client_code",
            feed_token: data.feedToken,
            script: "nse_cm|1594&nse_cm|10738&nse_cm|277&nse_cm|144&nse_cm|685"   //exchange|token for multi stocks use & seperator
        });

        web_socket.connect();
        web_socket.on('tick', receiveTick)

        function receiveTick(d) {
            console.log("Receive stock ticks::", d)
        }
    })
    .catch(ex => {
        console.log("EX::", ex)
    });

smart_api.setSessionExpiryHook(customSessionHook);

function customSessionHook() {
    console.log("User loggedout");
}

@admin Please help.

@tushar I too faced this issue before, I was not passing proper feedToken, Please verify that feedToken which you are passing is valid.
