Not the solution but a workaround: Why not converting your `OBJ` to `glTF`? Then you can use `GLTFLoader`, which has a built-in handling of `DracoLoader`.

Check out the following example: [https://threejs.org/examples/#webgl\_loader\_gltf\_extensions](https://threejs.org/examples/#webgl_loader_gltf_extensions)

Select the `Duck` model and then the `Draco` extension so see it in action.

Also see: [A .glb model loaded using GLTFLoader isn't compressing despite using DRACOLoader](https://discourse.threejs.org/t/a-glb-model-loaded-using-gltfloader-isnt-compressing-despite-using-dracoloader/2345/5?u=mugen87)
