Javascript io-发出JS对象会导致最大递归错误，然后不会'；我根本不发送

我有一个存储两个其他对象的对象。自上次加载页面以来，首次将此特定对象发送到服务器时，出现以下错误：

Uncaught RangeError: Maximum call stack size exceeded
at Function.[Symbol.hasInstance] (<anonymous>)
at r (socket.io.js:1)

未捕获范围错误：超过最大调用堆栈大小
在函数处。[Symbol.hasInstance]（
我发现了问题所在：只有在发送类实例时才会发生此错误。通过从一个实例提取数据并通过标准JavaScript对象文本发送数据，然后将数据重新应用到一个单独的实例才能解决问题。
那么，对象是否具有循环引用（例如，作为属性的父/子/根关系？）你能描述一下你要发送的对象的结构吗？我用了“this.”好几次，但除此之外，我不认为在没有看到你要发送的对象的情况下，除了思考可能的原因之外，你的问题没有什么可以回答的。请提供关于你要发送的结构的更多信息
