When I use Multi ControlNet

if choose other model

Research direction

Start with extensions/sd-webui-controlnet/scripts/controlnet.py around lines 850-851 and reproduce the error using Multi ControlNet and another model. Trace why detect_map is None before the arithmetic and Image.fromarray calls; done means the reported workflows complete without either traceback.
