Windows (\config\.metadata\.log):

MacOS (file:///Applications/Katalon%20Studio.app/Contents/MacOS/config/.metadata/.plugins/org.eclipse.ui.workbench/log):

Hi Didit,

Please also help to send me your test project also, I think it also somehow relates to your used Web Service object as well. If you can’t send it on this topic due to sensitive information, then please send it to me privately :slight_smile:

Regards

I don`t know if it helps but try to re-type url at your test object again or just add space in the end of url and send it.

After that restart Katalon Studio and try to launch your test case again
