On trying to update Alexa index.js to cater for the 'gpt-3.5-turbo-0301' Api conundrum

It’s quite possible that my expression of this issue is part of the problem but I am struggling with this and hence am offering it to the human community for discussion and a solution.

Below is an extract from a simple Alexa skill project. The uncommented code ( ‘text-davinci-003’) works. The comments are partly ‘gpt-3.5-turbo’'s suggestions although the messages: [array] comes from OpenAi’s documentation.

speakOutput’ is the puzzle but maybe that’s only part of the story.

Extracted from Alexa skill index.js
const AskOpenAIIntentHandler = {canHandle(handlerInput) {
return Alexa.getRequestType(handlerInput.requestEnvelope) === ‘IntentRequest’
&& Alexa.getIntentName(handlerInput.requestEnvelope) === ‘AskOpenAIIntent’;

async handle(handlerInput) {const question =
Alexa.getSlotValue(handlerInput.requestEnvelope, ‘question’);

const response = await openai.createCompletion({
//const response = await openai.createChatCompletion({

    //engine: 'textapi',
    //model: 'gpt-3.5-turbo-0301',
    model: 'text-davinci-003',
    prompt: question,
    messages: [
    { role: "system", content: "You are an all round good egg" },
    { role: "assistant", content: "How else may I help" },
    { role: "user", content: question },
    temperature: 0.5,
    max_tokens: 1024,
    top_p: 1,
    frequency_penalty: 0.0,
    presence_penalty: 0.0,
    n: 1, 
    stop: '\n',

const speakOutput = response.data.choices[0].text + 
  ' What more would you like to know?';
/* **either**
const systemMessage = response.data.choices[0].message;
const userMessage = systemMessage.context;
const speakOutput = `${userMessage} ${systemMessage.content} What more would you like to know? `;
const speakOutput = response.data.choices[0].message.content + 
   ' What more would you like to know?';

neither works

return handlerInput.responseBuilder
  .reprompt("What else can I help you with?")
