Annotation Image android

I have this code for the Annotation:

var thisView = Ti.UI.createView({
        width : 30,
        height : 30
    });
 
    var thisImage = Ti.UI.createImageView({
        width : 30,
        height : 30,
        image: '/icons/app-pin-avl.png'
    });
 
    var ant = gl_map.createAnnotation({
        latitude : latitude,
        longitude : longitude,
    });
 
    thisView.add(thisImage);
    ant.leftView = thisView;
    ant.image = thisView.toImage();
 
    $.mapview.addAnnotation(ant);

AnnotationProxy: (main) [56,25040] Unable to get the image from the path: {height=60, cropRect={x=0, width=60, height=60}, media=[object TiBlob], y=0, mimeType=image/png, x=0, width=60}

Already tried to change from toImage() to toImage().media, but still don't work.

Any ideas! Thanks!
