Issues with OpenAI Configuration in Firebase Functions - Error Reading Environment Variables

[luccahora]

Hi everyone,

I'm experiencing a couple of issues with configuring and using OpenAI in a Firebase function.

When trying to access the OpenAI API key in the openaiConfig.ts file, I get the error:

TypeError: Cannot read properties of undefined (reading 'key')

Here's the relevant part of the code:

import OpenAI from 'openai';
import * as functions from 'firebase-functions';

const openaiApiKey = functions.config().openai.key;

export const openai = new OpenAI({
    apiKey: openaiApiKey,
});

I set the environment variable using the command:

firebase functions:config:set openai.key="KEY"

Additional Information:

The functions execute normally when deployed to the cloud.

The issue occurs only when running locally with the command:
firebase emulators:start

Version:
firebase-admin: "^12.1.0",
firebase-functions: "^5.0.0",
openai: "^4.56.0"
