When trying to update an Epic through the API (be it a PATCH/PUT) it will throw an error if the Theme associated with it is inactive or deleted, the same if the owner is not active anymore. The problem is that the UI allows updates in both cases.
- Create a Theme
- Create an Epic
- Associate the Epic with the Theme
- On the Theme, mark Active as No (or delete it)
- Try to update the Epic title thru the UI
- Try to update the same thing thru API
The same test goes with the owner/user.
TBD by the Product team
The UI allows the update but the API doesn't.
Currently, there is no known workaround for this behavior. A workaround will be added here when available
