After updating the ComfyUI-LumaAI-API custom node, every image-to-video run failed with "GenerationsResource.create() got an unexpected keyword argument 'model'", regardless of which model was selected. The full traceback showed the error surfacing inside ComfyUI's execution pipeline during prompt processing. The node was passing a model kwarg that the installed ComfyUI core did not accept.

The reporter's own resolution: update ComfyUI itself. The node passes a model kwarg that only newer ComfyUI versions handle, so an updated custom node against an outdated ComfyUI core throws this TypeError. After updating ComfyUI, the error went away.
