我正在使用MongoDB Atlas来托管数据库，并且仅使用此功能就可以查询数据：

import { Nextapirequest,Nextapiresponse } from "next";

// models
import { Section } from "../../../models/Section";

// db connection
import { useDatabase } from "../../../middleware/useDatabase";

async function find(req: Nextapirequest,res: Nextapiresponse) {
  const { content } = req.query;
  const response = await Section.find({ contentType: content });
  res.send(response);
}

export default useDatabase(find);

中间件useDatabase的配置如下：

import * as mongoose from "mongoose";
import { Nextapirequest,Nextapiresponse } from "next";

export const useDatabase = handler => async (req: Nextapirequest,res: Nextapiresponse) => {
  if (mongoose.connections[0].readyState) return handler(req,res);
  // Using new database connection
  await mongoose.connect(process.env.MONGODB_URI,{
    useNewUrlParser: true,useFindAndmodify: false,useUnifiedTopology: true
  });

  return handler(req,res);
}

我第一次执行对api的访存查询时，效果很好，然后如果我编辑一些代码，保存并now dev重新编译代码，则再次执行查询时会出现此错误：

我该如何解决？谢谢！
