[Menduist]

Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

Since this commit:
359afb9

An empty apiKey ("") doesn't work anymore:

     42|     const client = new OpenAI({
       |                    ^
Error: Error: Missing credentials. Please pass an `apiKey`, `workloadIdentity`, `adminAPIKey`, or set the `OPENAI_API_KEY` or `OPENAI_ADMIN_KEY` environment variable.
     43|         apiKey: "",

To Reproduce

Create an OpenAI client with an empty apiKey
