ERROR saving with "embedding:" ->expected str, bytes or os.PathLike object, not NoneType UPDATE: (Workarround)

[amokiller]

hello everyone, I wanted to report a bug in the “saveimagewithmetadata” node. The error occurs when using “embedding:” in prompts (negative or positive).

tested with multiple text_encoder_nodes including basic ones (comfy-core)

It doesn't matter what name the embedding has or what path it is in. When you remove the “embedding:” the error disappears but the embedding is not loaded.

UPDATE:
first Sorry, I don't speak English hehe.
I have found where the error occurs.
You need a blank space before and after of “embedding:xxxx”
Example:

error:
,embedding:IllusN3g, embedding:IllusP0s,

fix:
,{white space here}embedding:IllusN3g{white space here},{white space here}embedding:IllusP0s{white space here},

this work, remember to put space before and after 'embedding:xxxx' :
, embedding:IllusN3g , embedding:IllusP0s ,

edit:
I have programming skills, but not in Python.
I think it should not be too difficult to “clean up” the text before calling get_embedding_file_path(place where the error occurs).

Thanks for all.

That fix didn't work for me (in ComfyUI) however setting a weight of 1 with brackets did.
e.g. (embedding:emb1:1), (embedding:other:1),

Works for me, ->

Remember "WHITE SPACE" before and after brackets in your case, the error is No Space before (of after) comma

"," <- error
" , " <- works

Hi! I have the same error, but I don't use any embeddings.
