如何解决WebRTC PeerConnection.getStats错误？

因此，我们有一个支持WebRTC的应用程序，它实际上是在建立会话，我们能够连接到它们，人们发布流，其他人订阅和取消订阅这些流，等等。但是我们不断从WebRTC收到错误，说“PeerConnection.getStats”。已经得到统计数据了错误发生在视频流本身。黑色背景上的白色文本，而不是视频

此外，在控制台日志中，我们还收到以下错误：

Uncaught TypeError: Cannot call method 'getStats' of undefined TB.min.js:208
PeerConnection.getStats: Already getting the stats! TB.min.js:54

你知道是什么引起的吗？我们如何从轮询统计数据关闭PeerConnection？？？？？提前感谢您的建议

我以前没有见过这种情况，但如果我猜这可能是因为您在订阅同一流之前订阅了多次
