I'm getting this too now, after a ComfyUI upgrade.

[fofr]

This error happens when the LayerDiffuse custom node is not loaded. I upgraded diffusers and LayerDiffuse and everything is working for me now on latest ComfyUI.

This error happens when the LayerDiffuse custom node is not loaded. I upgraded diffusers and LayerDiffuse and everything is working for me now on latest ComfyUI.

i have installed LayerDiffuse,why the error is still happen

you'd better to check your checkpoint model is SD 1.5 or SDXL. I met the same error when I used a SDXL model.
