Port, board and/or hardware

macOS, Node V20.11, Emscripten Port

MicroPython version

MicroPython v1.23.0-preview.324.g6634fea23.dirty on 2024-04-23; JS with Emscripten

Reproduction

fischmar@MACNP7L4XQC6C build-pyscript % node                
Welcome to Node.js v20.11.1.
Type ".help" for more information.
> const mp_mjs = await import("./micropython.mjs");
Uncaught:
TypeError [ERR_INVALID_ARG_TYPE]: The "paths[0]" argument must be of type string. Received undefined
    at validateString (node:internal/validators:162:11)
    at Module.resolve (node:path:1101:7) {
  code: 'ERR_INVALID_ARG_TYPE'
}

Expected behaviour

Import in node does not cause a fault.

Issuing node micropython.mjs correctly gives me the repl, so the mjs file seems to be ok.

Or maybe I'm missing something here? I was following the readme, section here:

const mp_mjs = await import("micropython.mjs");
const mp = await mp_mjs.loadMicroPython();

mp.runPython("print('hello world')");

Observed behaviour

see above

Additional Information

No, I've provided everything above.
