I am playing with the newly released UXP APIs and I think I found a bug. Or maybe I’m just using it wrong 😃 When I get a video clip track item through `Selection.getTrackItems()`, then get a parameter through `getComponentChain`, and then try to create a keyframe with `createKeyframe`, it throws an error - “Object does not exist.” This does not happen when I get the track item through `getVideoTrack` and `getTrackItems`. I prepared a small panel that shows off the issue: [uxp-sandbox/selection-create-keyframe at main · miscer/uxp-sandbox · GitHub](https://github.com/miscer/uxp-sandbox/tree/main/selection-create-keyframe) The panel can be loaded into UXP Dev Tools directly, there is no need to compile anything. There are instructions on how to replicate the bug in the panel. In the repository I’ve included a minimal project that has a single sequence with a single clip. I am using beta version 25.3.0, build 20. ---

Hi! Thanks so much for letting us know and the detailed descriptions - This is a bug, and we have investigated into the situation. **Update** : We have confirmed that this is fixed in today’s build.

Thanks for looking into it, but it seems to be still broken in build 27. I’m testing it with the panel I linked to in the first post. Also, I’m on Windows 11, if that’s relevant. ---

Turns out it takes longer time for windows build to fetch the fix… As you might noticed already, the fix is available in later win build. Please feel free to get the most recent update for Premiere Pro (Beta) and let us know if you are still hitting this issue! ---

I’ve tested it again with the most recent build (43) on both Windows and Mac and I’m getting the same error 😕 ---

Was this ever resolved? I am still seeing the issue in the beta. ---

Thanks for letting us know and sincere apologies for confusion! Yes, we have confirmed this was fixed in the earlier beta build - but is broken again in the most recent build. Based on current investigation, there seems to be unstable connectivity for the auto process of beta build to fetch the correct version of dependency with fix. That’s why the fix is available on and off. We are actively looking into the connectivity issue and will let you know once we get the fix stably back to the beta build again. ---

Confirmed that the fix was stably available in the beta build for the past few days.. Please feel free to get the most recent update from Creative Cloud for Premiere Pro(beta) and let us know if this is still happening. Thanks for your patience! ---
