Download image causing CORS block, must use nextjs backend to download image and upload to s3

Nextjs backend

const s3 = new AWS.S3({

    secretAccessKey: process.env.NEXT_PUBLIC_REACT_APP_AWS_SECRET_ACCESS_KEY || ""
  },
  region: process.env.NEXT_PUBLIC_REACT_APP_AWS_REGION || ""
});

const handler = async (req: NextApiRequest, res: NextApiResponse) => {
  const {text} = req.body;

  openai.createImage({prompt: text, n: 4, size: "256x256"})
