Error occurred when executing KSampler: 'NoneType' object has no attribute 'strength'

[tjohn88]

Hello! I can't resolve this error on many workflows with ControlNet Advanced nodes... It works without ControlNet Advanced... But how can I use it? I need to use Controlnets...

The error:

Error occurred when executing KSampler:

Since there is an already open issue for this, let's discuss this in that issue: https://github.com/Kosinkadink/ComfyUI-Advanced-ControlNet/issues/32

Just in case you haven't seen the other issue's comments, the problem is your ComfyUI is outdated by over a month - if you have tried updating and it still fails, that means your update failed. If everything you try to update (like a git pull) fails, you can start from a fresh copy of ComfyUI.
