Exception when using 'open-graph-website' tag

[huytnd]

I'm trying to use 'open-graph-website' tag for my page, and get this exception

The code I used

<open-graph-website site-name="@TitleSetting.Value.PublicWebsiteTitle"
                        title="@ViewBag.Title"
                        main-image="@(new OpenGraphImage(
                                    Url.AbsoluteContent("~/icons/open-graph-1200x630.png"),
                                    ContentType.Png,
                                    1200,
                                    630))"
                        determiner="OpenGraphDeterminer.Blank"></open-graph-website>

You need to have the following code in your Startup.cs Configure method:

application.UseBoilerplate();
