Question

我在express服务器正在运行的情况下将开发机器放在一夜之间，当我醒来时，我发现快递服务器因以下错误而崩溃：

C:\Users\James\Projects\nine-tails\server\node_modules\@mysql\xdevapi\lib\WorkQueue.js:72
        throw new Error('Queue is empty');
        ^

Error: Queue is empty

该错误来自xdevapi模块，但我似乎无法在文档的队列中找到任何内容，也不知道为什么发生此错误。

有什么建议吗？

编辑：以下是错误的整个日志：

除非X插件（MySQL服务器）发送一些带外或意外消息（这很奇怪），否则不会发生。

无论如何，要处理的内容并不多。也许您可以扩展日志记录基础结构（或使连接器中的响应处理程序有些混乱），也可以查看实际发生的情况。

如果您发现有趣的事情，建议您使用Connector for Node.js类别在官方MySQL issue tracker中创建错误报告。
