"Uninitialized constant" errors in Hyperstack: models and components cannot be found

Question

This is a weird error, because everything worked fine last week. When I wanted to start the app in development mode today I got multiple "Name Errors" saying that some classes cannot be found.

I have a component file called 'index.rb' with following content:

class Index < HyperComponent
  render do
    TABLE do
      THEAD do
        TR do
          TD { "ID" }
          # some other TD elements
        end
      end
      TBODY do
        SearchRequest.each do |search_request|
          SearchRequestItem(search_request: search_request)
        end
      end
    end
  end
end

Now I suddenly get this error message: uninitialized constant Index::SearchRequest. SearchRequest is a model. There is no component Index::SearchRequest. It worked last week, but suddenly this came up.

Any ideas? :)

Thanks in advance

Update: The first error message I see in the console is:
