I am initializing few details while creating work item.

I want to update those details before performing assignment.

So i am updating these values in pre DT of flow action of that assignment.

But, I am seeing values being set to pyWorkpage in tracer (while opening assignment), but these values were not being posted to clipboard, hence i am seeing stale date in UI(data set on case creation).

Tried solutions:
Added refresh condition on layout, where we are displaying these details. (Not worked)
manually reloading section from pre DT. (Not worked)
Tried with pre activity in flow action (Not worked)
Tried calling saving activity from pre DT, after setting these values (values were being updated and posted to clipboard and able to see updated data in UI. but not able to open assignment)

Unable to add attachment, but i made a post in PDN, please find reference link below
