Javascript 从页面到应用程序(NextJS)：REST.STATUS不是一个函数

我正在try 从Next 13.2.5更新到14.1.0，并使用app/api/example/route.js而不是pages/api/example.js.

我在下面的代码中得到错误TypeError: res.status is not a function at POST.

我的旧版本pages/api/example.js完全一样，但没有POST，所以我用了export async function(req, res)，它运行得很好.但在更新版本中try 了不同的方面(提到了here)，但我无法理解，我被困住了.任何帮助都将不胜感激.

import { Configuration, OpenAIApi } from "openai";

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

export async function POST(req, res) {
  if (!configuration.apiKey) {
    res.status(500).json({
      error: {
        message: "OpenAI API key not configured",
      },
    });
    return;
  }

  const { messages } = req.body;

  if (!Array.isArray(messages)) {
    res.status(400).json({
      error: {
        message: "Invalid conversation format",
      },
    });
    return;
  }

  try {
    const incomingMessages = req.body.messages || [];

    const messages = [
      {
        role: "system",
        content: `This is a roleplay. You are a participant in a market research study, simulating a 
        potential customer's perspective on a new product.
        `,
      },

      ...incomingMessages,
    ];

    const completion = await openai.createChatCompletion({
      model: "gpt-3.5-turbo",
      messages: messages,
      temperature: 0,
      max_tokens: 1000,
    });

    const responseMessage = completion.data.choices[0].message;
    const updatedConversationHistory = [...messages, responseMessage];

    res.status(200).json({ messages: updatedConversationHistory });
  } catch (error) {
    if (error.response) {
      console.error(error.response.status, error.response.data);
      res.status(error.response.status).json(error.response.data);
    } else {
      console.error(`Error with OpenAI API request: ${error.message}`);
      res.status(500).json({
        error: {
          message: "An error occurred during your request.",
        },
      });
    }
  }
}
