Messages property of openai.CreateCompletion function is not working

I used the code below for an Express app. However, it throws an error around the messages property in the openai.createCompletion function. Does anyone have an idea?

let conversation = [
  {
    role: 'system',
    content: 'You will follow the conversation and respond to the queries asked by the \'user\'\'s content. You will act as the assistant'
  }
];
app.post('/', async(req, res) => {
    try {
      const prompt = req.body.prompt;
      conversation.push({
        role: 'user',
        content: prompt
      }) 
    const response = await openai.createCompletion({
      model: 'text-davinci-003',
      // messages:  conversation.map(({ role, content }) => ({ role, content })),
      messages: conversation
    });
      conversation.push({
        role: 'assistant',
        content: response.data.choices[0].text
      })

    res.status(200).send({
      bot: response.data.choices[0].text
    });

  } catch (error) {
    console.error(error)
    res.status(500).send(error || 'Something went wrong');
  }
})

Davinci-003 does not have a chat mode, that is for conversational models such as gpt-3.5-turbo and gpt-4, try changing the model name to ‘gpt-3.5-turbo’

I modified to the code below, but I still get this error (Error: Request failed with status code 404)

Code:

let conversation = [
  {
    role: 'system',
    content: "You will follow the conversation and respond to the queries asked by the 'user's content. You will act as the assistant"
  }
];
app.post('/chat', async (req, res) => {
  try {
    // prompt+='user: ' +req.body.prompt + '\n'
    let prompt = req.body.prompt 
    conversation.push(
      {
        role: 'user',
        content: prompt
      }
    )
    const response = await openai.createCompletion({
      model: "gpt-3.5-turbo",
      messages: conversation,
      max_tokens:500
    });
    // prompt += 'assistant: ' + response.data.choices[0].text.trim() + '\n\n'
    // console.log(prompt)
    conversation.push(
      {
        role: 'assistant',
        content: response.data.choices[0].text
      })

    res.status(200).send({
      bot: response.data.choices[0].text
    });

  } catch (error) {
    console.error(error)
    res.status(500).send(error || 'Something went wrong');
  }
})```

Looks like you are calling the old creatcompletion function, try it like this

const completion = await openai.createChatCompletion({
    model: 'gpt-3.5-turbo',
    messages: [
      {
        role: 'user',
        content: 'what is the first online game to be played competitively?'
      }
    ]
  });
