Hello!
It seems like you misassigned the paperContour variable. It should be:

const paperContour = scanner.findPaperContour(cv.imread(image));

getCornerPoints accepts a contour as the parameter. You're passing the parsed image, not the contour.

Your final code should be:

window.addEventListener("load", () => {
    cv['onRuntimeInitialized'] = () => {
        const scanner = new jscanify();
        const image = document.getElementById("image");
        const paperContour = scanner.findPaperContour(cv.imread(image));
        const {
            topLeftCorner,
            topRightCorner,
            bottomLeftCorner,
            bottomRightCorner,
        } = scanner.getCornerPoints(paperContour, image);
        console.log("topLeftCorner", topLeftCorner);
        console.log("topRightCorner", topRightCorner);
        console.log("bottomLeftCorner", bottomLeftCorner);
        console.log("bottomRightCorner", bottomRightCorner);
    }
})

Hope this helps!
