HarmonyOS TLSSocket发送字节数组异常data is not string

关键代码：

try {
  let us:Uint8Array = packet.toArray()
  this.mSocket?.send(us, (err: BusinessError) => {
    if (err) {
      LogUtil.e(TAG, "发送数据失败:" + JSON.stringify(err))
    }
  })
} catch (e){
  LogUtil.e("handleSendData， err:"+JSON.stringify(e))//这里抛出异常：data is not string@6c4fa472
}
