hi there i get this error from this workflow:
[workflow.json](https://github.com/comfyanonymous/ComfyUI/files/13917762/workflow.json)

You're getting a nonetype error with the save_image function, which means the save image node is not receiving the input it expects.

Have you attempted to investigate what is being passed through that socket?

sorry for my ignorance but i don't know what is socket, and how to check it in comfyui with this workflow

I am receiving a very similar error

W10, RTX4090 24GBVRAM, i7-12700K, 32GB DDR5, Using Pinokio to 1 click run Comfy-UI.

I used a simpler workflow of mine and i have no issues, but when i use a complex workflow it seems I have the exact same error and my workflow crashes. Any help or guidance would be greatly appreciated.
