Thanks @Madalyn_Destafney In fact there is one mistake in my statement. They are not the custom fields. They are all out of the box fields. Is there a way not to allow users view those task-level OOTB fields, but at the same time allow them to upload files to the task?
Thanks - please could elaborate on where do you see "AssignedTo" and "Assignments"?I was checking the API Explorer but can only find the following but I think it might not be the one you referred to.....
This is brilliant! Thanks so much Chris for taking your time to share this.
I also use a Iterator as the step 6 to be able to output bundles so that I can do further manipulation on a non-aggregated level.
