msak preview :No preview properties are displayed

[mikko66]

Hello blogger, as shown in the picture, I used the MASK preview node and the prompt was no preview property. I updated comfyui and the system, but couldn't fix the problem. I downloaded a new node (ComfyUI_essentials) to upload the same error. Can you help me see what went wrong? Thank you very much. Puzzled me for a long time.
