Hey @allanokothdev, Emily here from Support Engineernig at Intercom 
You are seeing the error TypeError: null is not an object (evaluating 'IntercomEventEmitter.UNREAD_COUNT_CHANGE_NOTIFICATION') because you are likely referencing an internal or non-public API. The recommended way to track unread message count changes in Intercom's React Native SDK is:
- Use Intercom.getUnreadConversationCount() to fetch the current unread count.
- Listen for updates using the public event IntercomEvents.IntercomUnreadCountDidChange, not IntercomEventEmitter.UNREAD_COUNT_CHANGE_NOTIFICATION.
Example usage:
useEffect(() => { const countListener = Intercom.addEventListener( IntercomEvents.IntercomUnreadCountDidChange, (response) => { setCount(response.count as number); } ); return () => { countListener.remove(); };}, (]);
This approach is documented and supported. If you are using Expo, ensure you are not running in Expo Go, as custom native modules like Intercom require a custom dev client or EAS build.
It would also be recommended to use the latest version of the React Native module which you can find here
