In this topic you reported a problem in com.kms.katalon.core.execution.TestExecutionSocketServerEndpoint.
In another post "No application is started yet" shows in Web Testing @shunmatsu_begginer reported a problem in the com.kms.katalon.core.execution.TestExecutionSocketServerEndpoint as well. @duyluong replied at "No application is started yet" shows in Web Testing - #2 by duyluong that Katalon Team confirmed a bug and will fix it in next release. You may wait for their work.

I tried to modify the try/catch in Katalon but I don’t have read/write access to that code in TestExecutionSocketServerEndpoint. Should I try to modify this class elsewhere?
Do you want to modify TestExecutionSocketServerEndpoint for further investigation for yourself?
You can try do it by Groovy’s Metaprogramming feature. You can overwrite the run method implementation of the class with your code. Learn the official document:
http://groovy-lang.org/metaprogramming.html#metaprogramming_emc
Here is a sample project where I used the Metaprogramming feature in Katalon Studio.
You may be or may not be successful in overwriting the class and change its runtime behavior. I do not know. Just try and see.
However, even if you worked out in Metaprogramming, I suppose you would not be able to fix the root cause and consequently you can not use the Debugger in your project. You had better sit tight, wait for the Team to release the fix.
