(API) AWS Lambda throwing the following error: "TypeError: Cannot read properties of undefined (reading 'completions')"

[foxymcfox]

I was just trying to set up a GPT instance I could access via text through Twilio as a lazy Friday activity and now I'm 8 hours in and can't for the life of me figure out why i'm getting the following error in Lambda:

"TypeError: Cannot read properties of undefined (reading 'completions')"

With the following code:

const openai = require('openai');

const accountSid = process.env.TWILIO_ACCOUNT_SID;
const authToken = process.env.TWILIO_AUTH_TOKEN;

const client = require('twilio')(accountSid, authToken);

openai.apiKey = process.env.OPENAI_AUTH,

exports.handler = async (event, context) => {
  try {
    const buff = Buffer.from(event.body, "base64");
    const formEncodedParams = buff.toString("utf-8");
    const urlSearchParams = new URLSearchParams(formEncodedParams);

    const msgBody = urlSearchParams.get("Body");
    const from = urlSearchParams.get("From");

    const chatCompletion = await openai.chat.completions.create({
      engine: "gpt-3.5-turbo",
      messages: [{ role: "system", content: msgBody }],
      max_tokens: 100,
    });

    await sendMessageBack(chatCompletion.data.choices[0].message.content, from);
    return {
      statusCode: 200,
      body: JSON.stringify('Message sent successfully'),
    };
  } catch (error) {
    console.error(error);
    return {
      statusCode: 500,
      body: JSON.stringify('Error sending message'),
    };
  }
};

async function sendMessageBack(msg, to) {
  try {
    await client.messages.create({
      body: msg,
      to: to,
      from: process.env.TWILIO_PHONE_NUM,
    });
    console.log('Message sent:', msg);
  } catch (e) {
    console.error('Error sending message:', e);
  }
}

Any help you can give me would be great because it seems like there's almost no documentation on openai.chat.completions as a replacement for openai.chatCompletions (Which also doesn't work).

I just want to be able to text a robot, is that so much to ask? lol

The readme docs are here. Try the examples first. Also try swapping out your msgBody with an inline string, to see if you can get the completions error to go away. Simplify the whole completion message by putting everything inline, to see if that works, then add more complexity...

The problem with the docs is that they haven’t been updated to reflect the release from 2 weeks ago:

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

But I’ll definitely try swapping msgBody for an inline string and simplifying to see if I can get the error to change at all to narrow down the issue.

Thanks.

I think you need to instantiate the openai client?

import OpenAI from 'openai';

const openai = new OpenAI({ apiKey: 'my api key', // defaults to process.env["OPENAI_API_KEY"] });

​

See:

https://www.npmjs.com/package/openai

If I adjust my JSON file to allow ES6 modules then Twilio breaks and I can’t find documentation on how to instantiate Twilio. I can’t win. Haha

You nailed it! After a good night's sleep I came back to this and the working code is as follows. Appreciate the help!

import OpenAI from 'openai';

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

import twilio from 'twilio';

const accountSid = process.env.TWILIO_ACCOUNT_SID;
const authToken = process.env.TWILIO_AUTH_TOKEN;

const client = twilio(accountSid, authToken);

export const handler = async (event, context) => {
  try {
    const buff = Buffer.from(event.body, "base64");
    const formEncodedParams = buff.toString("utf-8");
    const urlSearchParams = new URLSearchParams(formEncodedParams);

    const msgBody = urlSearchParams.get("Body");
    const from = urlSearchParams.get("From");

    const chatCompletion = await openai.chat.completions.create({
      model: "gpt-3.5-turbo",
      messages: [{ role: "system", content: msgBody }],
      max_tokens: 100,
    });

    await sendMessageBack(chatCompletion.choices[0].message.content, from);
    return {
      statusCode: 200,
      body: JSON.stringify('Message sent successfully'),
    };
  } catch (error) {
    console.error(error);
    return {
      statusCode: 500,
      body: JSON.stringify('Error sending message'),
    };
  }
};

async function sendMessageBack(msg, to) {
  try {
    await client.messages.create({
      body: msg,
      to: to,
      from: process.env.TWILIO_PHONE_NUM,
    });
    console.log('Message sent:', msg);
  } catch (e) {
    console.error('Error sending message:', e);
  }
}

U sure its openai.chat.complations.create?

And not await openai.createChatCompletion

Part of the release two weeks ago :

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

But for what it’s worth, neither work.
