facebook can't resolve URL

Am trying to build a facebook share button, but I keep getting an error message inside the share popup screen when I click the button

Could not resolve object at URL http://localhost:8080/App/templates/property-template.xhtml?propertyId=1#

I tried to use encodeURI and encodeURIComponent but got same result.

am using jsf with javascript to accomplish this.

JSF

 <a href="#" class="btn btn-sm btn-round btn-o btn-facebook"
 onclick="share(window.location.href);"><span class="fa fa-facebook"></span> Facebook</a>

javascript

function share(url) {

    console.log(url);
    FB.ui({
        method : 'share',
        href : url,
    }, function(response) {
        if (response && !response.error_code) {
            alert('Posting completed.');
        } else {
            alert('Error while posting.');
        }
    });
}
