js通过ace接口调用led驱动，HdfIoServiceBind绑定服务失败

参考这篇文章https://ost.51cto.com/posts/10369进行js调用led驱动，ace通过HdfIoServiceBind绑定服务失败，单独写一个测试程序却能成功，openharmony小型系统LTS3.0.2，开发板是hi3516dv300-ipcamera_hispark_taurus。

报错代码段以及日志如下：

ace绑定服务失败，代码段以及日志如下:

JSIValue AppModule::ToggleLed(const JSIValue thisVal, const JSIValue *args, uint8_t argsNum)
{
    HILOG_INFO(HILOG_MODULE_ACE, "Ace ToggleLed%s\n", LED_SERVICE);
    struct HdfIoService *serv = HdfIoServiceBind(LED_SERVICE);
    if (serv == NULL) {
        HILOG_ERROR(HILOG_MODULE_ACE, "fail to get service2 %s\n", LED_SERVICE);
        return JSI::CreateUndefined();
    }
    HdfIoServiceRecycle(serv);
    return JSI::CreateUndefined();
}

测试程序却可以成功绑定，代码段以及日志：

int main(int argc, char **argv)
{
  int i;
  printf("myled service %s!\r\n", LED_SERVICE);
  /* 获取服务 */
  struct HdfIoService *serv = HdfIoServiceBind(LED_SERVICE);

  SendEvent(serv, atoi(argv[1]));
  HdfIoServiceRecycle(serv);
  printf("exit");
  return HDF_SUCCESS;
