Node Js not getting response for multiple instruments pass in subscribe for websocket

ZS0082

when i am creating an array dynamically and sending it to subscribe I am not getting any response. But when I am sending a static array to subscribe I am getting a response. Pls help.

here is my code.

//ForWebSocket
exports.connectSocket = function(req,res) {  
  const { id } = req.params;
  UserModels.getRequestToken(id, function(err, result){
      var accessToken = result.access_token;
      console.log("accessToken => "+ accessToken);
      var ticker = new KiteTicker({
          api_key: process.env.apiKey,
          access_token: accessToken
      });
           

      ticker.autoReconnect(true, 10, 5)
      ticker.connect();      
      ticker.on("connect", subscribe);
      ticker.on("ticks", onTicks);

      ticker.on("connect", function() {
        console.log("connect");
      });

      ticker.on("noreconnect", function() {
        console.log("noreconnect");
      });

      ticker.on("reconnecting", function(reconnect_interval, reconnections) {
        console.log("Reconnecting: attempt - ", reconnections, " innterval - ", reconnect_interval);
      });  

      function onTicks(ticks) {
          console.log("Ticks 2 => ", ticks);
          var data = ticks;
          for (let index = 0; index < data.length; index++) {
            var subscribRecords = new SubscribRecords(data[index]);
            InstrumentsModels.saveSubscribRecords(subscribRecords),function(err,result){

            };    
          }
      }

     <b class="Bold"> function subscribe() {
        InstrumentsModels.getInstrumentsSelected(function(err,result){
           var instrument= [];
            //var items = [260105,256265,21490690,21490946,21491202];
            for(var i =0; i < result.length; i++){              
              instrument.push(result[i].instrument_token);
            }
            ticker.subscribe(instrument);
            ticker.setMode(ticker.modeFull, instrument);
          });        
       }</b>
       
  });
   res.redirect('/'); 
}

Did you set onError and check?
Also, you can print the array that you are sending and check.

we have tried above both but no error accrue. the token List print same when we pass both way dynamic and static.
