How to use JSON mode in Next.js for a chat completion?

I am using npm openai package in Next.js to create a chat completion but its not accepting “response_format” as I want the reponse to be in JSON.
Kindly check code attached for the route.
`import { NextResponse } from “next/server”;
import OpenAI from “openai”;

const openai = new OpenAI({
apiKey: process.env.NEXT_PUBLIC_OPENAI_API_KEY,

export async function POST(request: Request) {
const { ingredients } = await request.json();

if (!ingredients)
return NextResponse.json({ message: “Ingredients not found.” });

const chatCompletion = await{
messages: [

Each recipe should include the following keys: 'title' for the title of the recipe, 'description' for the description, 'steps' for the step-by-step guide to preparation and cooking, 'time' for the total time required in minutes, 'ingredients' for the list of ingredients, 'cuisine' for the cuisine of the recipe, and 'calories' for the estimated calorie count per serving,

return NextResponse.json(chatCompletion);
