Trying to openai am I missing something?

    import OpenAI from 'openai'

    const openai = new OpenAI({
      baseURL: 'http://localhost:11434/v1',
      apiKey: 'ollama', // required but unused
    })

    const chatCompletion = await 
      openai.chat.completions.create({
      model: 'llama2',
      messages: [{ role: 'user', content: 'Why is the sky blue?' }],
    })

    console.log(completion.choices[0].message.content)

I am getting the below error:

    return new NotFoundError(status, error, message, headers);
                   ^
    NotFoundError: 404 404 page not found
