Spy object on active browser stopped working


When I use spy object on an active browser, it wont show me the capture object option. Therefore I am no longer able to capture any objects on an active browser. This suddenly stopped working for me. Closing/reopening Katalon Studio does not help. Note that we are able to do a spy object on a non active browser. See stack trace below.

I’ve had same issue just last week - i reinstalled chrome, katalon recorder and it seemed to work after that.
What happens when you right-click on the browser? does it show katalon recorder?

Mine works but if only i have Slack or some other program open… it somehow invoke that App and i switch to chrome and it works lol

Still I see few ppl with this issue and it needs to be fixed properly!

Perhaps another (invisible) Katalon Studio was up and listening to on your PC.

Why not you try Power off your PC and restart everything.
