Please mention that to name an output you must use something like:

io.Image.Output(display_name="images", tooltip=IMAGE_TOOLTIP)

And that

io.Image.Output("images", tooltip=IMAGE_TOOLTIP)

Is interpreted as id="images"

Also: which ComfyUI version is required for v3 API?

BTW: Migrating nodes that inherit from other nodes generates really confusing effects, like you see on the frontend the right schema, but the validation is fully messed. As the spec is moving to stateless classes I think the docs should mention that inheritance is discouraged. And for the record: the classes didn't call define_schema of the parent, so the problem is related to some magic under the hood.

Looks like this is 0.3.48, so we need to add requires-comfyui = ">=0.3.48"
