Hey!
No worries
I’m using UiPath 2018.4.3, however I do not think this is an issue with your version.
I checked in the forum and I’ve seen a couple of questions with regards to the same issue, please check the forum before creating a new question as you may find the solution in there
Check the answer marked as “Solution” as it could solve your issue: Try Catch Printing Exception Source - #4 by vvaidya
There is also this article but I haven’t seen any solution in there: How to get Exception source "Activity Description name" - #2 by aksh1yadav
Let me know if this helps!
Best,
Oriol
