Popup displayed when saving or running test

I’m using katalon 7.9.1
this pop window is displayed anytime when trying to save the test or during execution.


This is happening because you have errors in the script. You need to correct them first then run the tests.
In any case we dont have much info you gave us to help you but the cause is in the popup itself.
Solve the issues in your script and it will run fine.

it seems to me to have checked everything in the code, but I found nothing fishy that could generate the error.

I will check again.

thank you for reply
