OpenAi API Server error 500 text-curie-001 - node.js

Question

I have a site that is returning a server error 500 when requesting data from OpenAi api. I'm using the text-curie-001. I'm a newbie with this type of thing so I apologise in advance if I've got something totally wrong.
You can see in the console how the error shows: https://original-story-maker.vercel.app/
I'm using the free version of OpenAi if that makes any difference.
Here is the code that requests from api.
import { Configuration, OpenAIApi } from "openai";
const configuration = new Configuration({
apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);
export default async function (req, res) {
const completion = await openai.createCompletion("text-curie-001", {
// prompt: generatePrompt(req.body.animal),
prompt: "Write a story about " + req.body.employee + " wearing a " + req.body.wearing,
temperature: 0.9,
max_tokens: 720,
top_p: 1.0,
frequency_penalty: 0.0,
presence_penalty: 0.0
});
res.status(200).json({ result: completion.data.choices[0].text });
}
