一直在尝试使用openai API。在意识到我使用的是旧版API的语法后，我将其切换到了3. 5版本。现在似乎得到一个未定义的错误。不确定，但我可能又做错了语法方面的事情？对这个问题有什么想法吗？
错误代码：

PS C:\Demo> node index.js
undefined

字符串
代码：

import { Configuration, OpenAIApi } from "openai";

const configuration = new Configuration({
    organization: "Placeholder",
    apiKey: "Placeholder" 
});
  
const openai = new OpenAIApi(configuration);

const completion = await openai.createChatCompletion({  // Functions must be /v1/chat/completions compatible: 
  model: "gpt-3.5-turbo",  
  messages: [
    {role: "user", content: "How are you today?"},
  ]
});
console.log(completion.data.choices[0].text); // print text response from response object
