我最近遇到了一个问题，即每次只有1个发件人连接到我的自定义接收器时，会发送2个发件人连接事件。我在接收器调试控制台中收到以下错误。
cast_receiver.js:37 [ 2.456s] [cast.receiver.CastReceiverManager] Unexpected connected message for already connected sender: 14:client-20839cast_receiver.js:37 Ub
cast_receiver.js:37 [ 2.459s] [cast.receiver.CastMessageBus] Unexpected sender already registered [urn:x-cast:com.google.cast.media, 14:client-20839]cast_receiver.js:37 Ub
cast_receiver.js:37 [ 2.460s] [cast.receiver.CastMessageBus] Unexpected sender already registered [urn:x-cast:com.massivision.test, 14:client-20839]cast_receiver.js:37 Ub
我几周后没有对我的发件人或收件人代码进行任何更改，然后这种情况在大约一天前开始发生。我希望这是由cast_receiver.js的变化引起的。还有其他人遇到同样的问题吗？
