"openai-streams and slash or openai api(?) bug".js

import { OpenAI } from "openai-streams";
import { yieldStream } from "yield-stream";

const stream = await OpenAI(
  "chat",
  {
    model: "gpt-3.5-turbo",
    n: 2,
    temperature: 1,
    messages: [{ role: "user", content: "hi" }],
  },
  { apiKey: API_KEY, mode: "raw" }
);

const DECODER = new TextDecoder();

for await (const chunk of yieldStream(stream)) {
  const decoded = JSON.parse(DECODER.decode(chunk));

  console.log(decoded);
}

output ends with this weird error object
