Resolving OpenAI API Authentication Errors in Azure Functions by Correctly Setting Environment Variables

Problem:
Your application hosted on Azure is not able to authenticate with the OpenAI API despite having the API key set as an environment variable.

Cause:
The environment variable name set in Azure does not match the one used in the application code.

Solution:
Ensure that the name of the environment variable set in Azure matches the one your application is trying to access.

Step-by-step guide:

1. Go to the Azure Functions settings screen.

2. Change the name of the environment variable ChatGPT_key to OPENAI_API_KEY. The value remains the same.

3. Save the changes and restart Azure Functions.

After these steps, Azure Functions should correctly recognize the OPENAI_API_KEY environment variable, and your application should successfully authenticate with the OpenAI API.
