当我尝试将视频切换到后置摄像头时，出现以下错误：
OpenTok:SessionDispatcher:error A stream does not exist with the id of 58b71fe2-87ef-4e7f-b087-e230af1b1692, for stream#deleted message! +0ms
OpenTok:Publisher:error onStreamAvailableError OT_CONSTRAINTS_NOT_SATISFIED: It's not possible to satisfy one or more constraints passed into the getUserMedia function (getUserMedia error: OverconstrainedError) +0ms
OpenTok:GlobalExceptionHandler:error OT.exception :: title: Unable to Publish (1500) msg: GetUserMedia +0ms
Unhandled Promise Rejection: OT_CONSTRAINTS_NOT_SATISFIED: It's not possible to satisfy one or more constraints passed into the getUserMedia function (getUserMedia error: OverconstrainedError)
此错误不一致，有时相机开关确实起作用。有人知道这个错误是什么意思吗？预先感谢。
