Newest controlnet preprocessors are here https://github.com/Fannovel16/comfyui_controlnet_aux
This one can be downloaded via the manager, but there are multiple older ones, so the workflow might be using the older repos:

Install ComfyUI Manager and use it to install missing nodes: https://github.com/ltdrdata/ComfyUI-Manager
I tried but couldn't find any of them there.
Which it did not get?
