小程序使用LivePusher组件推流，调用关闭推流stop时，经常会报以下这些错误，日志如下

{"errno":102, "errMsg":"operateXWebLivePusher:fail:access denied}

{"errno":102", errMsg":"operateLivePusher:fail jsapi has no permission, event=operateLivePusher, runningState=background, permissionMsg=permission got, detail=jsapi has no permission}

请问是什么原因？如何避免？
