Got an error when I tried to use the Openai SDK in Node.js

I am trying to use Openai api with nodejs, I follow the tutorial and want to add a simple gpt text completion feauture using the openai SDK, but I got an error says: /node_modules/openai/core.js:44 const isJSON = contentType?.includes('application/json') || contentType?.includes('application/vnd.api+json');

It results in a crash of the app, I didn't find out why.

This is the code:

import OpenAI from 'openai';

const openai = new OpenAI({
    apiKey: process.env.OPENAI_API_KEY,
});

export const gptResponse = async (req, res) => {
    try {
        const { message } = req.body;
        const getResponse = await openai.chat.completions.create({
            model: 'gpt-3.5-turbo',
            messages: [
                {
                    role: 'system',
                    content: 'You are a helpful assistant.',
                },
                {
                    role: 'user',
                    content: message,
                },
            ],
        });
        console.log(getResponse.data.choices[0].message.content);
        return res.json(getResponse.data.choices[0].message.content);
    } catch (err) {
        console.log(err);
        return res.status(400).send('Error. Try again.');
    }
};

Solution

This code will work.

Save as `demo.js'

import OpenAI from 'openai';

const openai = new OpenAI({
    apiKey: process.env.OPENAI_API_KEY,
});

const requestData = {
    model: 'gpt-3.5-turbo',
    messages: [
        {
            role: 'system',
            content: 'You are a helpful assistant.',
        },
        {
            role: 'user',
            content: 'Hello!',
        },
    ],
};

async function getGPTResponse() {
    try {
        const response = await openai.chat.completions.create(requestData);
        console.log("Response from OpenAI:", response.choices[0].message.content);
    } catch (error) {
        console.error("Error:", error.message);
    }
}

getGPTResponse();

In package.json

{
  "type": "module",
  "dependencies": {
    "openai": "^4.28.0"
  }
}

Install dependencies

npm install

Run it

node demo.js

Result

Confirm by Postman

You can see the response message's hierarchy
