Smart Service Error Handling

Question

Hi Guys, 
 
 There is any generic way to catch an error returned by a smart service? 
 For instance, for "Send Email" Smart Service if I encapsulate this node in a sub-process, when an error is returned the exception flow is activated. I want to know if this behavior can be applied in a generic way for other smart services. 
 
 Best Regards

Hi fredericom as per my understanding, as far it's about Java, for building a Smart Service, yes we can handle the exceptions using try-catch block in Java, because we want to avoid termination of the code Abnormally. 
 
Now when it comes to Appian, we can go for Timer, like if the email did not sent within expected/business time frame, then need to for exception flow. 
 
Hope this will help you.
