Hi Samitha,
If you want to log the full stacktrace in jaggery, you can log it like
below.
log.error(e) //print the stacktrace
log.error('My error message') //print the message
(If you are using the latest jaggery release, it supports logging both
the message and the exception
Hi Praminda,
Thanks for the suggestion. That approach seems suitable here.

Hi Samitha,
LBYL(Look Bfore You Leap) and EAFP(Easier to Ask Forgiveness than
Permission) is the two ways used to error checking. Different languages
have different preferences. Ex: Python prefers EAFP (try-catch) over LBYL
(if-else).

Hi Tharik,

block by following your approach. But it seems impossible to log or get the
stack trace of the exception there. But as in the example in yours,

catch block by following approach in the code below.

Hi Sachith,
So do you suppose to catch the error thrown from java, finally at the
jaggery or even later at javascript?
Anyway if we are printing the full stacktrace in Java side, what is the
objective of throwing it to the jaggery ?
Is it to indicate to the front end that an error was occurred in
Hi Samitha,
>From what I understand, you need to both print the full stack trace and

using Jaggery in between the above two. So my question is what is the best
practice in Exception handling and error logging in such a this scenario.
