Welcome to the RingCentral Community

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()
});

function subscribe_for_telephony_notification() {
    subscription.setEventFilters(['/restapi/v1.0/account/~/telephony/sessions'])
        .register()
        .then(function(subscriptionResponse) {
            console.log(subscriptionResponse);
            console.log("Ready to receive Telephony via PubNub.")
        })
        .catch(function(e) {
            console.error(e);
            throw e;
        });
}

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