Subscription not created when using production

Question

I have a simple app that just logs out responses from the telephony subscription. It works great in the Sandbox, but after I graduated it and use it in Production (and changing credentials), it does not create a subscription (I use this to check: https://developers.ringcentral.com/api-reference/Subscriptions/listSubscriptions). But I don't see any errors in the console.It does print out "Ready to receive Telephony via PubNub." so it seems like it worked, but I don't see a subscription listed. Just wondering how I diagnose this further, or if I am missing something.const RC   = require('@ringcentral/sdk').SDK
const Subs = require('@ringcentral/subscriptions').Subscriptions
require('dotenv').config();

var rcsdk = new RC({
    'server':       process.env.RC_SERVER_URL,
    'clientId':     process.env.RC_CLIENT_ID,
    'clientSecret': process.env.RC_CLIENT_SECRET
});
var platform = rcsdk.platform();
platform.login({
    'username':  process.env.RC_USERNAME,
    'password':  process.env.RC_PASSWORD,
    'extension': process.env.RC_EXTENSION
})

var subscriptions = new Subs({ sdk: rcsdk });
var subscription = subscriptions.createSubscription({
    pollInterval: 10 * 1000, renewHandicapMs: 2 * 60 * 1000
});

platform.on(platform.events.loginSuccess, () => {
    subscribe_for_telephony_notification()
});

subscription.on(subscription.events.notification, function(msg) {
    console.log(msg.body);
});

First of all, you don't need to call this line. The SDK does auto refresh and keep the subscription active as long as you keep the subscription instance.

var subscription = subscriptions.createSubscription(
{ pollInterval: 10 * 1000, renewHandicapMs: 2 * 60 * 1000 }
);

Then add and call this function to list all subscriptions created by your app

async function readAllSubscriptions() {
  try {
    var resp = await platform.get('/restapi/v1.0/subscription')
    var jsonObj = await resp.json()
    if (jsonObj.records.length > 0){
      for (var record of jsonObj.records) {
        if (record.deliveryMode.transportType == 'PubNub'){
          console.log(record)
        }
      }
    }else{
      console.log("No subscription")
    }
  }catch(e) {
    console.log(e.message)
  }
}
