I’m using user defined java class in order to perform encryption and trying to have it inside a try catch, it says that try catch doesn’t support user defined java class.

is there different approach to implement try catch since this is a big workflow.

Hi! Tushar,

That’s a good point. The Try-Catch steps do not support some steps in Process Studio. For these steps you have to use error handling if possible.

You can use Try-Catch steps for the supported steps. You could also modularize your workflow by using child workflows.
