Error handling in Apps from Faulted process

Hello,
after triggering a process using an Apps event Start Process, I want to show an error message taken from the Exception if the process fails (uncaught Exception with no Global Exception Handler set).

This is how it’s configured right now:

It correctly works if the process is started as Attended, but when the type is set to Unattended both variables Error Type and Error Message are always empty, resulting in an empty error message.

How can I make it work for Unattended processes?

@Regina_Stefano ,

Are you returning error message into our argument from process ?

Thanks,
Arvind

No, I’m using the built-in variables in Start Process event.
