Hi!
Some compressed models don’t work and throw an error after applying mesh compression.
Applied the compression using gltf-pipeline:
gltf-pipeline -i tmp/tmp.gltf -o optimized.glb --binary --draco.compressMeshes --draco.compressionLevel 10

Am I missing something? Did anyone had the same issue?
Using CesiumJs v1.68.
