Globalhandler errorInfo is not Catched // Message Box not displayed

Hello there,

I am currently doing the RPA Developer Course in the Academy.

One of the tasks was to prepare the GlobalHandler.

When I try to give out a message box it gives me the following error: “Message Box: The calling thread cannot access this object because a different thread owns it.”

Also I think the GlobalHandler doesnt receive the full errorInfo.

Can you help me?GlobalHandler.xaml (7.4 KB) Main.xaml (22.2 KB)

did we Try mention like this errorinfo.Exception.Message.ToString

Cheers @Khar

Hi, I had the same problem.
If I execute the solved example, it works. But when I try myself, fail.
Maybe is beacuse I’m using System.Activities v19.10.1 instead of v19.4.0

Hi @Khar,

Please ensure the used packages are update, even i had faced the same issue & resolved by updating the packages.
