The images output is never filled, and any link from it fails at runtime. This also blocks the node inside ComfyUI's native Start Loop / End Loop, where a node in the loop body must reach End Loop to pass validation and needs a working output to connect to its terminations input. Two optional inputs share one socket, so image_a is preferred and image_b is the fallback.
