THREE.JS gltf model loading, but missing node data & areas of mesh?

Question

I'm trying to load my donut model using Three.js gltf loader, and I'm perfectly able to add the model onto the canvas, however the model doesn't load with it's geometry node data (sprinkles), as well as some mesh of the icing is either missing or z-fighting. I'm wondering if this is a problem with how the model was built, with how the model is being loaded, with how parcel is copying the model file, or even how i exported the glb file ? Model in blender
Model on canvas

Here is the code I'm using to load my model. (there is no problem getting the model onto the canvas, the donut has it's coloring however not sprinkles (geometry node data) and appears to be z fighting or missing parts of the icing mesh)

const donutUrl = new URL('../assets/big_donut.glb', import.meta.url)
const assetLoader = new GLTFLoader()
assetLoader.load(donutUrl.href, function(gltf){
    const model = gltf.scene
    model.scale.set(2,2,2)
    model.position.set(0, 1, 0)
    scene.add(model)
}, undefined, function(err){
    console.log(err)
})

Any help is appreciated, Thank you!
