nodejs 报错 connection error - uncaughtException: Cannot read properties of undefined (reading 'query')

当你在Node.js中使用数据库连接时，可能会遇到"connection error - uncaughtException: Cannot read properties of undefined (reading 'query')"的错误。这个错误通常是由于未处理的异常导致的。在Node.js中，我们可以使用process对象的'uncaughtException'事件来捕获未处理的异常，并进行适当的处理。代码示例中，使用process.on('uncaughtException', function (err) {...})来监听'uncaughtException'事件，并在发生未处理的异常时进行处理。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
