I'm using standard fields (large text) and picklist and trying to map values from the custom fields on a custom Issue form to the same custom fields on a custom Project form - and whether adding to a data structure used in a Create JSON step, or directly mapping from the webook data to the fields in a Update Record module I am getting a 422 error - whether that value is present, or even null.
It sounds like 422 is Workfront's way of saying I get what you are asking me and it looks to be correctly structured, but I don't like / understand it? Why would this be happening - we have lots of other text fields that map just fine.... but not these three.
Super frustrating when there's an error, but no solution provided. And search hasn't helped either - so maybe the community can 🙂
