How to resolve requires without `.js` extension in a very basic NPM resolver?

I have an NPM resolver that without caching that expects everything to be in a node_modules folder, mostly copied from deno cli https://gist.github.com/rust-play/fbd49c87332ee27b3d217bb1e0005462 I can successfully require lodash, but one of the npm libraries I'm trying to require imports a babel library like so

var _interopRequireDefault = require("@babel/runtime/helpers/interopRequireDefault");

var _interopRequireDefault = require("@babel/runtime/helpers/interopRequireDefault");

It seems like it's failing to resolve the module, cause it panics at thread 'main' panicked at 'called Result::unwrap() on an Err value: Error: Cannot find module '@babel/runtime/helpers/interopRequireDefault'

Bootstrapping a minimal node-compatible runtime

I'm trying to bootstrap a minimal node-compatible runtime, so I've basically been copying and pasting MainWorker and removing things I don't need like napi or kv

However when it crashes on JsRuntime::new

Is there anything I seem to be missing that could cause this error?
