Vertex texture fetch support is required to render primitives with per-instance attributes

CesiumJS

Hello Cesium Community,

I am working on a CesiumJS application that is built using Webpack. My goal is to add a rectangle primitive with an image on it. While the code works perfectly in a simple Cesium environment, I encounter the following runtime error when running the application within my Webpack setup:Vertex texture fetch support is required to render primitives with per-instance attributes. The maximum number of vertex texture image units must be greater than zero.

Error

I have ensured that my WebGL capabilities support vertex texture fetch (verified Max Vertex Texture Image Units: 32). Additionally, I am using the same version of Cesium in both environments, but still encountering the issue in the Webpack-based application.

Any insights or suggestions on how to resolve this runtime error would be greatly appreciated.

Thank you!
