当 nodejs 运行时间长之后再去请求 nodejs 的接口会报错

Error: Packets out of order. Got: 0 Expected: 9

code: 'PROTOCOL_PACKETS_OUT_OF_ORDER',
fatal: true

数据库文件database.js部分代码

const mysql = require('mysql');
const fs = require('fs');
const secret = require('./secret.json');

const isDev = process.env.NODE_ENV === 'development';

const connection = mysql.createConnection({
  host: 'localhost',
  user: isDev ? secret.mysql.dev.username : secret.mysql.product.username,
  password: isDev ? secret.mysql.dev.password : secret.mysql.product.password,
  database: "hpchat",
  connectTimeout: 1000 * 60 * 10,
})

module.exports = async res => {
  let response
  if (res) response = require('./response.js')(res);
  const query = (sql, params, callback) => {
    return new Promise(async (resolve) => {
      // check mysql connection is timeout
      if (connection.state === 'disconnected') {
        await connection.connect();
      }
      connection.query(sql, params, (err, result) => {
        if (err) {
          if (callback) callback(err);

          }
          const file = fs.readFileSync('error_log.txt');
          const path = res.req.url;
          const message = `[${new Date().toLocaleString()}] ${path} | ${sql} | ${err.message}\n`;
          fs.writeFileSync('error_log.txt', message + file);
