WebView example does not work in the version 0.10.0 (build 6044).

In response to a question in the forum, “WebView” get into the following error when I want to run the example.

LOG:

Sample Code (from fuse learn)
<App Theme="Native" Background="#333">
    <JavaScript>
            module.exports = {
                onPageLoaded : function(res) {
                    console.log("WebView arrived at "+ JSON.parse(res.json).url);
            }
        };
