imread() throws error "abort(ReferenceError: document is not defined). Build with -s ASSERTIONS=1 for more info."

[ggenellina]

Based upon the node commonjs example:

const { getOpenCv } = require("./opencv.js");

async function main() {
  const { cv } = await getOpenCv();
  console.log("OpenCV.js is ready!");
  console.log(cv.getBuildInformation());
  const inputImage = cv.imread("Lenna.png");
  console.log("imread, done");
}

main();

Output:

(build info, as expected)
(a very long block of obfuscated code)

abort(ReferenceError: document is not defined). Build with -s ASSERTIONS=1 for more info.
(Use node --trace-uncaught ... to show where the exception was thrown)
