Detailed description

After compiling OpenCV.js following the tutorial, running the following code:

import cv from "/home/sid/Documents/opencv/build_js/bin/opencv.js"


const cv2 = await cv;

let dictionary = cv2.getPredefinedDictionary(cv2.DICT_6X6_250);
let size = {width: 5, height: 7};
let squareLength = 0.04;
let board = new cv2.aruco_CharucoBoard(size, squareLength, 0.02, dictionary, new cv2.Mat());

board.getChessboardCorners()

results in an error:

node:internal/process/esm_loader:40
      internalBinding('errors').triggerUncaughtException(
                                ^

Node.js v20.9.0

Steps to reproduce

1. Clone opencv and opencv_contrib
2. Build: emcmake python3 ./platforms/js/build_js.py build_js --cmake_option="-DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules"
3. Run my code with node test.js

Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files (videos, images, onnx, etc)
