I am trying to load a dummy node to ComfyUI. I have put the file in the custom_nodes folder and I don't see why it should fail as all the packages are installed and the node effectively does nothing. I have also set security to weak in my ComfyUI manager... still nothing. Any idea?

class GcImagePass:
    @classmethod
    def INPUT_TYPES(s):
        return {
            "required": {
            },
            "optional": {
                "image": ("IMAGE",),
            },
        }
    RETURN_TYPES = ("IMAGE",)
    FUNCTION = "passthrough"
    CATEGORY = "image"
    DESCRIPTION = """

    def passthrough(self, image=None):
        return image,
