HarmonyOS 接口获取数据number，定义对象属性为string可以直接获取，使用时报错

报错信息如下：

axios.post<OutDTO<UserBean>, AxiosResponse<OutDTO<UserBean>>, PhpSignRequestBean>(UrlAddress.getPassportBaseURL() +
  '/api/passport/auth', UrlAddress.phpSignRequestParams(loginRequestBean))
  .then((response: AxiosResponse) => {
    console.info("result:" + JSON.stringify(response.data));
    let outDTO: OutDTO<UserBean> = response.data as OutDTO<UserBean>;
    if (outDTO.result) {
      setUserInfo(outDTO.data as UserBean)
      this.jumpToMain();
    } else {
      ToastUtil.showToast(outDTO.msg)
    }
    this.isShowLoading = false;
  })
  .catch((error: AxiosError) => {
    ToastUtil.showToast(error.message)
    this.isShowLoading = false;
  });

问题发生在获取UserBean.uid。
