Hi there,
Thank you very much for your topic. Please note that it may take a little while before a member of our community or from Katalon team responds to you.
Thanks!
Hi @mpajarito ,
Welcome to our community. Can you please help share the KS version you are upgrading, your code if possible, your device or driver version, mobile-testing or web-testing, … ? Thank you
Hi @Elly_Tran
The version that I have upgrade is 9.4.0 ; Neverthless, I was working with the version 9.3.1 both web testing.
the error is
You probably have somewhere the code, matchingFiles.size(). The message is stating that KS cannot perform this statement because there is nothing in “matchingFiles”. Can we see the code in this area?
Can we also see your error log? main menu Help > Error Log
