Error while deserializing header: incomplete metadata, file not fully covered

Hello, I am trying to run a workflow using Expression Editor (PHM) and I am receiving the error:

“Error while deserializing header: incomplete metadata, file not fully covered”

My workflow has only three elements: load image > Expression Editor (PHM) > Preview Image

I have tried many different images with the same result and I can find nothing online that directs me to what may be wrong.

Can someone give some advice on what mistake I may have made?

I am running Comfyui v0.3.59 on windows 11 - GeForce RTX 2060.

File "D:\ComfyUI_windows_portable\ComfyUI\comfy\utils.py", line 59, in load_torch_file
    with safetensors.safe_open(ckpt, framework="pt", device=device.type) as f:
         ~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
safetensors_rust.SafetensorError: Error while deserializing header: incomplete metadata, file not fully covered

Thank you

Had you already tried to update the python and modules? That usually solve my code error problems. :nerd_face:

Thank you for your replay.

Yes I did update python and removed and reinstalled the models being used. In fact, I did a clean install of Comfyui and still had the same result. I am wondering if it has something to do with my hardware - I am running windows 11 laptop with an RTX 2060 card with 8 gig vram…it is slow but normally eventually gets the job done. this is the only error I have encountered so far and there is very little on the net about it so it appears to be somewhat unique.

This custom node doesn’t even uses a model? :thinking:

Are you using one of these flows?
