Error with LM Studio hosted OpenAI compatible embedding model

[Else00]

I was trying to use an LM Studio hosted embeddings model but I have problem adding it.

First: i manually tried the embeddings model with RapidAPI:
Request

}

  ],

    "total_tokens": 0
  }
}

I already configured the LLM phi-4 from LM Studio with the url http://host.docker.internal:1234/v1/chat/completions and it works fine.

Then i tried to configure the embedding model, i selected OpenAl-compatible APl embedder, i used http://host.docker.internal:1234 as url because i have seen that in the code the /v1/embeddings is automatically added.

LM Studio log:
