I have a Search doctype (that uses a IMeta interface). I try to return a Search viewmodel in a Index method. I'm getting the same error as Leon (https://our.umbraco.com/forum/using-umbraco-and-getting-started/111299-search-view-model-exception) but i don't quite get how to fix this issue.

For anyone to help you should add some additional details about what you have in your view and your search viewmodel 🙂
