Failing to upgrade the OpenAI Node.js SDK from v3 to v4

Question

I'm trying to update my app from Angular 15 and "openai": "^3.2.1" to Angular 17 and "openai": ^4.24.1".

I cannot understand what is missing. No errors occurred.

Followed links:

1. https://platform.openai.com/docs/guides/text-generation/completions-api

2. https://github.com/openai/openai-node/discussions/217

3. OpenAI API error: "The model `text-davinci-003` has been deprecated"

4. OpenAI ChatGPT (GPT-3.5) API error: "This is a chat model and not supported in the v1/completions endpoint"

Old version:

import { Configuration, OpenAIApi } from 'openai';
  readonly configuration = new Configuration({
    organization: environment.openAIOrganization,
    apiKey: environment.openAIToken,
  });


  readonly openai = new OpenAIApi(this.configuration);

  //#region -- GENERATE CHATGPT MSG --
  async getDataFromOpenAI(text: string): Promise<any> {
    try {
      const completion = await this.openai.createCompletion({
        model: "text-davinci-003",
        prompt: text,
        temperature: 0.9,
        max_tokens: 62,
      },
        {
          headers: {
            'Content-Type': 'application/json',
            //'baseOptions': 'User-Agent',
            'Authorization': 'Bearer ' + environment.openAIToken,
            'Access-Control-Allow-Origin': '*'
          }
        })

      return completion.data.choices[0].text
    }
    catch (error) {
      console.error('error.message', error);
    }
  }
  //#endregion

New version:

import OpenAI from 'openai';



 async generateSms() {
    try {
      let completion = await this.openai.completions.create({
        model: 'gpt-3.5-turbo-instruct',
        prompt: 'Create a happy birthday message',
        temperature: 0.5,
      });
      console.log(completion);
      console.log(completion.choices[0].text);
    } catch (e) {
      console.error('generateSms => ', e);      
    }
  } 
  

I created a new key but is only returning [null]

Last used in API KEY is updating: last used 12/jan

The initialization is different with the OpenAI Node.js SDK v4 than with v3.

If you're using the OpenAI Node.js SDK v4, then the following is the correct initialization:

const OpenAI = require("openai");

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

You did the completion part correctly, as follows:

let completion = await this.openai.completions.create({
    model: "gpt-3.5-turbo-instruct",
    prompt: "Say this is a test.",
});
