responses.create parameter types

[seratch]

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 you have previous_response_id in the parameter list for responses.create method, the TypeScript compiler is not able to determine which of the overloaded methods to use.

To Reproduce

More specifically, the response object is any with an error in the following code:

import OpenAI from "openai";
const client = new OpenAI();

const instructions = `You're a helpful assistant.`;

let previousResponseId: string | undefined = undefined;
const outputs: string[] = [];

while (outputs.length < 5) {
  const input = `Write a haiku about programming. Don't repeat the words and phrases.`;
  // response' implicitly has type 'any' because it does not have a type annotation and is referenced directly or indirectly in its own initializer.ts(7022)
  const response = await client.responses.create({
    model: "gpt-4.1",
    instructions,
    input,
    previous_response_id: previousResponseId,
  });
  previousResponseId = response.id;
  outputs.push(response.output_text);
}

console.log(JSON.stringify(outputs, null, 2));

A work around is to explicitly specify the parameter object type like this:

import { ResponseCreateParamsNonStreaming } from "openai/resources/responses/responses";

  // ....

  const params: ResponseCreateParamsNonStreaming = {
    model: "gpt-4.1",
    instructions,
    input,
    previous_response_id: previousResponseId,
    stream: false,
  };
  const response = await client.responses.create(params);
