Hi,

Is the issue related to the version of Katalon Studio?

If so, could you suggest me the version which for sure will not replicate the issue!!!

Thanks,

I was having the same issue using KS 6.3.3 running against Chrome - I think the underlying cause was an update to the latest Chrome version (Version 78.0.3904.70 (Official Build) (64-bit)), I fixed the issue by updating the Chrome web driver (in KS: Tools > Update WebDrivers > Chrome)
