A script allows you to capture both the fact that execution failed (via an exception) and _why_ it occurred, which is strictly **more** information than is available in a transaction group handshake.

I would not pursue transaction groups for this purpose.  
Try adding catch blocks that explicitly capture both Java and Python exceptions:

> [@Catch IOException?](https://forum.inductiveautomation.com/t/catch-ioexception/18612/3):
>
> Consider using two except blocks, as jython’s standard Exception won’t catch pure java exceptions. Like so: import java.lang.Exception try: # something something something except Exception, e: # jython exception except java.lang.Exception, e: # java exception
