NovaSkin Resource Pack Editor - 3D Preview Not Working

Hello,

I’m having an issue with the NovaSkin Resource Pack Editor:

https://minecraft.novaskin.me/resourcepacks

Normally, this page should display a 3D player model that allows users to edit Minecraft armor textures and preview how the equipment looks when worn (see reference screenshots below).

However, the 3D viewer is currently not working correctly. Instead, I receive the following error message:

Project google_vignette not found

Screenshots attached for comparison between the expected behavior and the current broken state.
