I'd like to store workflow instance data locally (on prem) for easier access / integration, and also for reopening/amending a previous instance. Our organisation hardly uses SharePoint so I don't fancy using lists.

Hence I prefer to store all data in an Oracle database using a JSON call.

Is there a way to generate the JSON body with <all> instance data (a LOT) without having to compile this manually, field by field?

Many thanks in advance!
