Lines keep processing after Normal index 2412 is out of bounds Error causing Socket hanging

[Apidcloud]

Hello!

Uploading the file attached below ends up making the server hang. After a few seconds there's an actual error "Normal index 2412 is out of bounds Error", but it still hangs the whole server -- so future requests never complete. Might be related to https://github.com/CesiumGS/obj2gltf/issues/287

Here's a minimum reproduction repo: https://github.com/Apidcloud/nestjs-sigbus-example/tree/obj-hanging

To test it:

• clone or download the repo (in obj-hanging branch) above
• npm ci
• npm run start:dev
• curl localhost:3000/hello -- to check the server is running locally and you are able to reach it
• curl localhost:3000 -- after a few seconds this will reply with the error "Normal index 2412 is out of bounds Error"
• curl localhost:3000/hello -- never completes because the server is completely hanging

From what I can understand, even after the error is thrown, the lines keep being processed:

And actually even before that is thrown, the reject keeps being called interchangeably with also this error "Expected cartesian to be typeof object, actual typeof was undefined":

}

The very first error shows up at normal 2412 (and you can see it keeps reading and rejecting):

Any news regarding this? It happened again today with the following model: another-faulty-model.glb.zip
