连接 MySQL 数据库时出错：数据包乱序。获得：1 预期：0

Question

我正在开发一个使用 MySQL 作为数据库的 Next.js 项目。当我运行应用程序时，几次运行后遇到以下错误：“连接到数据库时出错：错误：数据包乱序。得到：1 预期：0”。但是，构建应用程序后，并不会出现该错误，并且仅在本地开发环境中发生。

这是完整的错误堆栈跟踪：

如果您能了解此错误发生的原因以及如何修复它，我将不胜感激。谢谢！

这是我的 db.js

import mysql from 'mysql';

// Keeping the variable name connection instead of pool :') NVM, The deadline is tight

//Updating DB Connection:
const connection = mysql.createPool({
  connectionLimit: 10,
  host: process.env.DB_HOST,
  port: process.env.DB_PORT,
  user: process.env.DB_USER,
  password: process.env.DB_PASSWORD,
  database: process.env.DB_NAME,
  multipleStatements: true,
  connectTimeout: 60000,
});

connection.getConnection((err) => {
  if (err) {
    console.error('Error connecting to database:', err);
  } else {
    console.log('Connected to database');
  }
});

export default connection;

我尝试过调整connectionLimit和其他配置，但都没有解决问题。

我正在使用 dotnet 8.0，unitofwork 和repositorypattern 遇到相同的错误

问题是工作单元提交是异步的

我更改为同步并且成功了
