Trying to run this as-is, but I get this error:

Prompt outputs failed validation
LoraLoaderModelOnly:

• Value not in list: lora_name: 'Hyper-SDXL-2steps-lora.safetensors' not in []

I can't select any lora_name; it's stuck on undefined. The file Hyper-SDXL-2steps-lora.safetensors is in ComfyUI\models\checkpoints, so I don't understand why it's not found. I don't know if this is related, but I tried putting in the custom node, but I get errors from the ComfyUI terminal:
