How to deal with multiple exception with the try and catch module

Hello Everyone
I have two business exception to make.
This is what i did in the try block

and this is what i did in the catch block

All i get is the text in the throw activity (“Dossier introuvable”) It doesn’t pass the catch activity.
Can anybody tell me why
thank you

You need to catch specific exceptions, a business exception bundles all exceptions together, and you will keep getting the same results.

Catch specific exceptions and for each exception add a new catch block, you wont need an if activity then.
