jsPDF: Incomplete or corrupt PNG file

I’m trying to add an image to my PDF document but get this error Uncaught Error: Incomplete or corrupt PNG file in this line doc.addImage(imgData, 'PNG', 15, 40, 180, 160); , this happens when I add imgData var to my PDF file but not when i add imgPDF var for test.

Any idea cuz this happens

        var zip = new JSZip();
        var img = zip.folder("documets").folder("products");
        var row = "txtRow";

        var imgData = value['data'];
        var imgPDF = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAQAAAADCAIAAAA7ljmRAAAAGElEQVQIW2P4DwcMDAxAfBvMAhEQMYgcACEHG8ELxtbPAAAAAElFTkSuQmCC';

        var doc = new jsPDF('landscape');

        doc.text(20, 20, 'This is the default font.');
        doc.addImage(imgData, 'PNG', 15, 40, 180, 160);

        var pdf = doc.output();

        imgData = imgData.replace(/^data:image\/(png|jpg);base64,/, '');
        img.file("file.png", imgData, {base64: true});
        img.file("file.pdf", pdf,{binary: true});



    zip.file("products.csv", row);
    var content = zip.generate({type:"blob"});
    //FileSaver.js
    saveAs(content, "csv.zip");
