Error between 2 User Interfaces using interface for communications.

Development Programming & Scripting UI

Parent Widget has a menu anchor and an interface (Popup) to manage Communication between child widgets. Now I added an exit prompt popup and used the interface to toggle open and close on the parent widget menu anchor.

It’s working, but for some reason it’s throwing a Blueprint Runtime Error: “Accessed None trying to read property ExitPopup.” In this case, “ExitPopup” is a menu anchor containing a child widget.

It’s working, but it’s throwing an error.

How can I fix it?
