Actually I want to create custom fields inside Processing Exception.
Like, There are already few system variables like ProcessingException.Reason, ProcessingException.message,etc.
So I want to create another field like ProcessingException.[CustomFields].
So is there any way we can create those.
these fields are Properties from classes / DataTransferObjects (dto definitions) which are not extensible out-of-box without touching their internal definitions. Also the Ui (e.g. Orchestrator) is aligned on this.
have a look at the data property of an exception, for setting additonal markers
