Unsure how to connect an api using nodejs - node.js

Question

I'm trying to connect the openai api into my app but I'm not sure why it's not working. From my frontend, I have a createUserData that receives an input and then stores it to my MongoDB database. But now, I want to send that input that I received to the openai API and get a response based on what they said. I tried implementing it here but it crashed on me with this error:
UnhandledPromiseRejectionWarning: Error: Request failed with status code 401

For some reason I crash when I try and call this API, am I doing it wrong?
Right now I just want to log whatever the response I get from the API, once I'm able to do that then I will store it to the database as well. But I can't even log it as I get an error. Here is my code:
const { Configuration, OpenAIApi } = require("openai");
// create new user data
const createUserData = async (req, res) => {
const {id, scores, transcript} = req.body
const user_id = req.user._id
console.log(user_id)
const configuration = new Configuration({
apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAIApi(configuration);
const response = await openai.createCompletion({
model: "text-davinci-002",
prompt: "Provide personal feedback for me and give me tips: " + transcript,
temperature: 0.7,
max_tokens: 256,
top_p: 1,
frequency_penalty: 0,
presence_penalty: 0,
});
console.log(response)
const newUserData = new UserData({
id: id,
scores: scores,
transcript: transcript,
user_id: user_id
})
// add doc to db
try {
await newUserData.save()
} catch (error) {
res.status(400).json({error: error.message})
}
console.log('POST:', newUserData)
return res.status(201).json({user_data: newUserData})
}
