I am getting error mentioned in the title, i have tried all the solution, but when manually edit the video tag of the linkedln learning by adding crossOrigin = 'Anonymous' and then executing below code i am able download screenshot, but when add this code player.setAttribute(crossOrigin,'Anonymous'); then i am getting error.

Please could anyone tell the possible solution,

    const title = "untitled";
    const player = document.getElementsByTagName("video")[0];
    const canvas = document.createElement("canvas");
    canvas.width = player.videoWidth;
    canvas.height = player.videoHeight;
    canvas.getContext("2d").drawImage(player, 0, 0, canvas.width, canvas.height);

    const downloadElement = document.createElement("a");
    downloadElement.download = title;

    canvas.toBlob((blob) => {
        downloadElement.href = URL.createObjectURL(blob);
        downloadElement.click();
    }, "image/png");
