My source code is add follow:

var fs = require('fs');
var Steam = require('steam');
var crypto = require('crypto');

var serverlist = [] //server list here
Steam.servers = serverlist;

var steamClient = new Steam.SteamClient();
var steamUser = new Steam.SteamUser(steamClient);

steamClient.connect();

steamUser.on('updateMachineAuth', function (sentry, callback) {
    console.log('writing to file sentry');
    fs.writeFileSync('sentry', sentry.bytes);
    callback({ sha_file: getSHA1(sentry.bytes) });
});

function getSHA1(bytes) {
    var shasum = crypto.createHash('sha1');
    shasum.end(bytes);
    return shasum.read();
}

steamClient.on('connected', function () {    
    steamUser.logOn({
        account_name: “XXXXXXXX”,
        password: “XXXXXXXX”,
        // un-comment this when providing secondary auth-code from email
        auth_code: ‘XXX’,
        sha_sentryfile: getSHA1(fs.readFileSync('sentry'))
    });
});

steamUser.on('loggedOn', function () {
    console.log('Logged in!');
});


steamClient.on('debug', function (response) {
    console.log("debug: " + response);
});

steamClient.on('logOnResponse', function (response) {
    console.log(">>logOnResponse");
    console.log(response);

if (response.eresult == Steam.EResult.OK) {
    console.log('Logged in!');
    // Your code here
}

});

steamClient.on('error', function (error) {
    console.log(error.stack);
    alert("yes error");
});

steamClient.on('servers', function (servers) {
    alert(servers);
    // fs.writeFile('servers', JSON.stringify(servers));
});

steamClient.on('disconnected', function (s) {
    alert(s);
});

The error that is being yield, undefined is not a function is happening because you are calling the function alert in node

That is not valid, as in node there is no function that is called like that, and since you have that function also in the errorHandler then the application dies.

If you were to delete the function alert of if you created and "alert" function that would console.log() what is happening the error should dissapear.

Try adding this function to your code or delete all of the alert functions:

const alert = () => {
  console.log(arguments)
}
