hmm, i think the problem is probably needing to initialize the module first, but, i actually think that is an outdated version. There has been some bugs in the draco compression libs, but idk much about that. Or the relationship between draco, gltf, and basis, but they were talking about it here.
.Consider adding gzip or brotli compression for Draco and Basis WASM binaries
labris linked this one , probably better than anything else.
