在UmbracoVirtualNodeRouteHandler中找不到内容时如何返回Umbraco 404页面

Question

I'm using UmbracoVirtualNodeRouteHandler to do use some custom logic to find my Umbraco Content. This works great except for when I don't find the content. When I don't find content, I want to show the Umbraco 404 page .

protected override IPublishedContent FindContent(RequestContext requestContext, UmbracoContext umbracoContext)
    {
        var content = findMyContent();
        //attempt 1
        return content; //even if content is null
        //end attempt 1

        //attempt 2
        if(content == null)
        {
            throw new HttpException(404, "Blogpost not found");
        }

        return content;
        //end attempt 2
    }

Attempt 1 results in the default unstyled 404 page saying
"The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."

Attempt 2 results in showing my custom error 500 page.

How do I show my custom Umbraco 404 page when I don't find content?

Did you try to use the configuration in umbracoSettings.config ?

You can configure a custom node for the 404 page by referencing the node ID, GUID or XPATH:

<errors>
    <error404>1234</error404>  
</errors>
<!--
The value for error pages can be:
* A content item's integer ID   (example: 1234)
* A content item's GUID ID      (example: 26C1D84F-C900-4D53-B167-E25CC489DAC8)
* An XPath statement            (example: //errorPages[@nodeName='My cool error']
-->
