ant-design-vue3.0 自定义表单验证 错误提示词为什么不在界面上显示

Question

     let validate_account_name = async (_rule, value) => {
      if (value === "") {
        return Promise.reject("不能为空");
      } else {
        var params = new URLSearchParams();
        params.append("name", value);
        axios
          .post(store_state.url + "points/isPointsAccountNameExist", params)
          .then((response) => {
            if (response.data == "find") {
              //已存在
              return Promise.reject("not ok");
            } else {
              return Promise.resolve();
            }
          });
      }
    };

    const rule_validate = {
      points_account_name: [
        {
          validator: validate_account_name,
          trigger: "change",
        },
      ],
    };
