Error on SaveWithMetadata

[Oninaig]

When passing images into SaveWithMetadata, I will wind up with the following error:

Error occurred when executing SaveImageWithMetaData:

expected str, bytes or os.PathLike object, not NoneType

Would you give me the workflow file?

[BouTschang]

Sorry but I have the same problem. Is it fixed?

[nkchocoai]

@BouTschang Not fixed yet. It would be helpful if you could attach the workflow file.

Same issue too, was working fine, no changes then suddenly stopped working yesterday:

Error occurred when executing SaveImageWithMetaData: expected str, bytes or os.PathLike object, not NoneType

Sorry i can't attach the workflow

Same problem here, just began today, with rel. 0f9c2a7

(I'm sending also the workflow I'm using)

The error log:

Quite strangely, it didn't happen again, after reloading Stability Matrix and this version of ComfyUI...

[nkchocoai]

@Vik71it

Error.json

It looks like the prompt contains “embedding:hoge” and the embedding file does not exist, so it is outputting an error.

[Pycpik]

I have the same error each time I use an (existing) embedding. Tried with embeddings in ComfyUI\models\embeddings or in my old A1111 install with extra_model_paths.

Nice node by the way :)
