Get list of all wall types in project

I’m new to dynamo. In Revit 2023 I developed a dynamo graph that takes the layer materials from all wall types and pastes them into a multiline type based shared parameter. I used a clockwork node “all family types of category” to retrieve all family types. This node no longer works in 2024 so I was hoping to create something of my own with out of the box dynamo nodes. I have tried this but there seems to be problems in getting the type name. I would appreciate any guidance with this issue. See below for an image of my original graph that no longer works.

See the image below for my futile attempt at replacing the clockwork node.
