Unable to set value of a 2D point component parameter

Premiere Pro
1

When I try to set the value of a 2D point parameter (such as Position in the Motion group) through the UXP API (createKeyframe, createSetValueAction) I get an error - “Error: Illegal Parameter type”.

Simple numeric values (such as Scale) work fine. I am able to get the value of the parameter - it returns an array with two numbers, as expected. But if I pass a similar array to the set value action, I get the error.

Here’s a panel to reproduce the bug, together with a Premiere project: uxp-sandbox/set-2d-point-value at main · miscer/uxp-sandbox · GitHub. I’m using beta build 30 at the moment.

Hi!

This happens because createKeyFrame() is looking for PointF Object for point parameter value creation, so doing

const newPoint = await ppro.PointF(0,0);
const keyframe = param.createKeyframe(newPoint);

should resolve the “Illegal Parameter Type” error

Please let me know if you are still seeing any issue!

Thanks for trying out UXP!

Thanks, using PointF instead of an array works :slight_smile:
