ERROR | query parameter | array of strings in VectorStoreSearch

[MwSpaceLLC]

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

When using the OpenAI SDK to search a vector store, sending an array of query strings (as stated in the SDK’s TypeScript definition and the official documentation) causes a server error (HTTP 500).

Link to documentation: Open AI Vector Storage Search | Array

To Reproduce

Steps to reproduce the behavior:

Use the following code (where openai is an instance of OpenAI initialized with a valid API key).

Notice the HTTP 500 error in response.

const openai = new OpenAI({ apiKey: inSessionUserActive.OpenAiToken });

const results = await openai.vectorStores.search({
  vector_store_id: "vector_store.id",
  query: [
    "allowed per passenger",
    "How many woodchucks are allowed per passenger?"
  ]
});

Code snippets

The OpenAI SDK TypeScript definition indicates an array of strings should be valid:

.... openai\src\resources\vector-stores\vector-stores.ts

export interface VectorStoreSearchParams {
  /**
   * A query string for a search
   */
  query: string | Array<string>;
}

OS

Node version

It seems to be a bug on Open AI API and not on node.js package, using the raw HTTP request following the cURL from the docs it also fails!

It works just fine with a string instead of an array of strings on query
