Uncaught TypeMismatchError: Failed to execute 'drawImage' in 'CanvasRenderingContext2D'

Question

I am having problems with the following snippet:

var o = $("#inserted_motive").find("span");
    $.contains(document.documentElement, o[0]) ? b.fillText(m, i, h) : b.drawImage(d, i, h, e, f);
    var p = a.toDataURL("image/png");
    window.open(p)
}), $(function () {
    $("#tabs").tabs()
});

The following error will appear:

Uncaught TypeMismatchError: Failed to execute 'drawImage' on 'CanvasRenderingContext2D': the first argument provided is either a null or invalid HTMLImageElement, HTMLCanvasElement, or HTMLVideoElement.

also answer the question;

 $("#creator").click(function () {
    var a = document.getElementById("final_image"),
        b = a.getContext("2d"),
        c = document.getElementById("shirt_main_canvas"),
        d = document.getElementById("inserted_image");
    b.drawImage(c, 0, 0);
    var e = $("#inserted_image").width(),
        f = $("#inserted_image").height(),
        g = $("#inserted_motive").position(),
        h = g.top,
        i = g.left,
        j = $("#inserted_motive span").css("font-size"),
        k = $("#inserted_motive span").css("font-family"),
        l = $("#inserted_motive span").css("color"),
        m = $("#inserted_motive span").text(),
        n = j + " " + k;

You should check that yours is #inserted_imagein your html, because it seems like it is none of:

• valid HTMLImageElement element
• HTMLCanvasElement element
• HTMLVideoElement object
