comfyui_controlnet_aux: Error: "Message class can only inherit from Message"

I know that this issue also existed in previous version of the extension and i never managed to get it working with methods mentioned earlier, so I’m gonna leave this there.

What I already tried:

• Do Comfy install in a venv
• Clean venv and install everything manually
• Clean install python and reinstall everything

My setup (something might mess things up and that’s why it’s not working):

• Pyenv-win (used to manage python versions)
• venv
• manual ComfyUI install (via git clone)
• manual extension install (via install.bat file)

The error:
