BUG: setValue fails in Position property
It is not possible to set the Position property of an item using ExtendScript on Premiere 2020.
Doing a getValue() returns an array, but when trying to do a setValue with an array gives an 'Illegal parameter type' error. This is not the case in Premiere 2019, where this code works perfectly:
this code will throw an error in Premiere 2020 but work flawlessly in 2019. Position property is therefore completely inaccessible, as well as other properties that requiere an array.
setValue() works fine in PPro 14.x ("2020"), if New World isn't on; it fails, even in PPro 13.x ("2019"), if New World is on.
We're tracking this issue as DVAPR-4220968; I'll update the SDK Forum, and this thread, with our progress.
