image problem :Returning null drawable reference

hi i make RSS feed program for Android

my problem is that image doesn't appear and give me that error message in the console :

"[WARN][TiDrawableReference( 479)] (main) [387,6928] Unknown image resource type: Object[]. Returning null drawable reference"

my code for that part of image are 2 parts the first are in rss file

var items = xml.documentElement.getElementsByTagName("item");
        var data = [];
 
        for (var i = 0; i < items.length; i++) {
            var item = items.item(i);
            var image;
            try {
            var image = item.getElementsByTagName("description").item(0).text;
 
           var patt1=/([a-z\-_0-9\/\:\.]*\.(jpg|jpeg|png|gif))/ig;
           var urlMatch = image.match(patt1);
           var imagesrc = TiConvert.toString(urlMatch);
           console.log("reg ex -----------------------" + urlMatch);
 
 
            } catch (e) {
                image = '';
            }
 
            data.push({
                title: getRssText(item, 'title'),
                link: getRssText(item, 'link'),
                pubDate: parseDate(getRssText(item, 'pubDate')),
                image: urlMatch
            });
 
        }

and the second are at the view which suppose to view that image and other data :

var imageview = Ti.UI.createImageView({
        image: item.image,
        height: 42, 
        width: 68, 
        left: 5,
        top: 3
    });

thanks in advance .
