SocialSharing-PhoneGap-Plugin: Failed to find configured root that contains

I am getting the following error when trying to share a file from a remote URL.

Here is my code.

var options = {
          message: 'share this', // not supported on some apps (Facebook, Instagram)
          subject: 'the subject', // fi. for email
          files: ["http://ngcordova.com/img/ngcordova-logo.png"], // an array of filenames either locally or remotely
          url: 'http://ngcordova.com/',
          chooserTitle: 'Pick an app' // Android only, you can override the default share sheet title
        }

        var onSuccess = function (result) {
          alert("Share completed? " + result.completed); // On Android apps mostly return false even while it's true
          alert("Shared to app: " + result.app); // On Android result.app is currently empty. On iOS it's empty when sharing is cancelled (result.completed=false)
        }

        var onError = function (msg) {
          alert("Sharing failed with message: " + msg);
        }

        window.plugins.socialsharing.shareWithOptions(options, onSuccess, onError);
