Comfy UI / Stable Diffusion error

Nobody has claimed this yet.

Hi All, can anyone help me, below is the error i get whenever i press the Queue Prompt in Comfy UI

`r:

'ModuleList' object has no attribute '1'

raise AttributeError(f"'{type(self).__name__}' object has no attribute '{name}'")`

Start by reproducing the Queue Prompt failure and tracing the stack from comfy/controlnet.py pre_run through comfy/utils.py set_attr and the referenced ComfyUI execution files. Check why the control model lookup requests the ModuleList attribute "1"; done means the reported workflow completes without this AttributeError.
