The ui.js file is responsible for the user interface and the main execution of the program. It doesn't seem to directly interact with the API endpoint. However, it does import and use the runAgent function from ./modules/interactiveAgent, which might be using the API endpoint.

To ensure the new environment variable OPENAI_BASE_PATH is used for setting the API endpoint, you should check the runAgent function in the interactiveAgent module. If the API endpoint is set there, modify it to use the new environment variable OPENAI_BASE_PATH.

If the runAgent function doesn't set the API endpoint, then no changes are needed in this file.

To solve this task, we need to modify the callGPT function in the modules/gpt.js file to use the new environment variable OPENAI_BASE_PATH for setting the API endpoint.

Here is a step-by-step plan:

1. Import the OPENAI_BASE_PATH from the environment variables at the top of the file, right after the OPENAI_API_KEY is imported. This can be done by adding the following line of code:

const OPENAI_BASE_PATH = process.env.OPENAI_BASE_PATH;

2. Modify the Configuration object to include the OPENAI_BASE_PATH as the base path for the API. This can be done by changing the following lines of code:

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});

to:

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
  basePath: OPENAI_BASE_PATH,
});

This will set the base path for the OpenAI API to the value of the OPENAI_BASE_PATH environment variable.

Please note that this change assumes that the OPENAI_BASE_PATH environment variable is correctly set in the .env file and that the OpenAI library supports the basePath configuration option. If the OpenAI library does not support this option, you may need to modify the library code or find a different way to set the API endpoint.

To solve this task, you need to add the new environment variable OPENAI_BASE_PATH into the .env file. This variable will hold the value of the custom API endpoint.

Here is how you can do it:

1. Open the .env file.
2. Add the following line at the end of the file:

OPENAI_BASE_PATH=your_custom_api_endpoint

Replace your_custom_api_endpoint with the actual API endpoint you want to use.

Please note that the .env file is usually not committed to the repository for security reasons. Therefore, each developer or environment should create their own .env file and set the OPENAI_BASE_PATH variable accordingly.
