Error: Node type <node> undefined

[Polygoningenieur]

Hi, thanks for the addon!

I installed the addon V1.5.7 in Blender 4.2 on Win 11 Pro 64-bit.
I installed it with git clone https://github.com/AIGODLIKE/ComfyUI-BlenderAI-node --recursive into the C:\Users\<user>\AppData\Roaming\Blender Foundation\Blender\4.2\scripts\addons folder.

This is the install log in Blender:

I connect to a running ComfyUI instance.

But when I choose any node tree, I only get "Error: Node Type ... undefined" errors:

This happens for all Node Trees and Node Groups. Also, after this, the Ctrl-A Add-Node menu is empty:

These are the other addons I have installed:

And these are the other extensions I have installed:

Can you please help me fix this issue? Thanks! :)

The same happens when I install the addon on a fresh portable Version of Blender 4.2 and 4.3 beta. I also testen Blender 4.0 and 4.1.
I have multiple Pythons installed on the system, used for other things. Could that be a reason?

Try the latest develop repo. May be fixed.
