[Urgent] 500 when requesting a file from browser.

I need to display images on canvas, so I have used the following snippet. The request is reaching the server but I get the following trace. Unable to make sense out of it, if any of you can help out, it would be great.

function getImage(file_name, num_pages) {

myimage = new Image();

            myimage.onload = function () {

                //console.log();

                alert("Vineeth");

                canvas.width = myimage.width;

                canvas.height = myimage.height;

                ctx.drawImage(myimage, 0, 0);

            }

            myimage.src = window.origin + "{% static '' %}" + file_name + "-" + '1.ppm';

            //"https://cdn.images.express.co.uk/img/dynamic/67/590x/secondary/Frank-Lampard-Chelsea-Derby-1922384.jpg?r=1560987023999";

            //window.origin + "{%static ''%}" + file_name + "-" + '1.ppm';

            console.log(myimage.src);

}

Folks, please have a look at this.
