若WebSocket后端出现错误时，WebSockect连接错误则有可能出错：

var ws = new WebSocket("wss://ap.fundebug.com/api/events/count");

Fundebug插件捕获的这个错误之后，开发者将受到报警，然后可以在我们的控制台查看错误详情：

Fundebug插件捕获的错误数据如下：

{
    "notifierVersion": "1.5.1",
    "userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36",

    }
}

silentWebsocket

如果你不需要监控WebSocket连接错误，则可以将silentWebsocket属性设为true。

if ("fundebug" in window) {
   fundebug.silentWebsocket = true;
}
