Reproducible in script:

const draco3d = require("draco3d");
let decoderModulePromise = Promise.resolve(draco3d.createDecoderModule({}));
console.log({decoderModulePromise})

Node.js v18.1.0

@expenses - Were you able to find a quick workaround? (For example, hardcode the path)

[expenses]

No, I didn't look very hard into this. An easy workaround seems like it should be possible though.

[lilleyse]

Seems to only happen in Node 18. Node 16 works fine. I tested draco 1.5.2 for both.

Assuming this problem isn't caused by gltf-pipeline in some way, could you submit to bug report to the draco repo?

Done: google/draco#888

[FrankGalligan]

Can you try running with "--no-experimental-fetch" command line flag?

We think this has to deal with emscripten-core/emscripten#16913

I can confirm that this fixes the problem for me.
