Hi all,

I get a wierd error while developing a custom Dojo widget. The widget works just fine in edit mode, but when I try to view the start page on my test site I get a 404. The logged error message is "Unable to establish the template category of the template of type: '...StandardPageController'" and it is logged by a class called EPiServer.Scanning.Internal.DefaultTemplateExtractor[0]

When i remove the section i appSettings.json the page loads as usual, but the widget in edit mode is not found by the CMS.

"CmsUI": {
  "ProtectedModule": {
     "Items": [
      {
         "Name": "MyWidget"
      }
    ]
   }
 }

What am I missing?

The error is thrown from EPiServer.Scanning.Internal.DefaultTemplateExtractor.Extract(Type) when none of the implemented interfaces of the type is IRenderTemplate<T>.

In some case, it's automatically resolved by clean and rebuild the solution.
