Error on registering the subscribtion to an event

[Mirsagatov]

I am trying to subscribe to a ring-central event via @sdk/subscriptions.

useEffect(() => {
    if (!subscriptions || !selectedAccountId || !selectedCompanyId) return;

    const subscription = subscriptions.createSubscription();

    subscription.on(subscription.events.notification, handleTelephonySessionNotification);

    subscription
      .setEventFilters(["/restapi/v1.0/account/~/extension/~/telephony/sessions"])
      .register()
      .then((subscription) => {
        setTelephonySessionsSubscription(subscription);
      })
      .catch((err) => console.error("Failed to register to telephony session notifications", err));

    return () => {
      telephonySessionsSubscription?.revoke();
    };
  }, [subscriptions, selectedAccountId, selectedCompanyId]);

However, I get the following error due to .register():

RingCentralSoftphone.tsx:265 Failed to register to telephony session notifications TypeError: Cannot read properties of undefined (reading 'addEventListener')

When I click the source of the error, this is where I end up:

 setupWsEventListener() {
    this.wse.ws.addEventListener("message", this.eventListener);
  }

I am using React + Typescript + Vite. I have installed nodePolyfills for the ring central sdk to even work.
I found no mention of such an issue anywhere on the Internet.
