PK.Telegram.Activities receive message error:object referance not set to an instance of an object

Hi. Is anybody using PK.Telegram.activities? I recently found out that the receive message activity giving out exception error (System.NullReferanceException)with message of object referance not set to an instance of an object. Need expert help to solve this. Thanks in advance

May be i used it wrongly. Can someone out there teach me how to use it?

Weird. Now it functions normally.

As far as i can see the package is deprecated and not in active development anymore: RPA Listings - Collections, Integration Packs | UiPath Marketplace
You might have to consider other packages in the future

Any recommendation of package for that?
