Appium vision：1.0.0-beta.2，官网下载 scroll_to 方法报错
请问大家用的什么版本？报错吗？能否降级？这样就不会有这么多奇怪的问题。

public WebElement scroll_to(String text) {
        RemoteWebElement element = null;
        try {
          text = text.replaceAll("\"", "\\\""); // quotes must be escaped.
          final String jsonString = "{\"script\":\"mobile: find\",\"args\":[[\"scroll\",[[3,\""
              + text + "\"]],[[7,\"" + text + "\"]]]]}";
          final String id = driver.getSessionId().toString();
          final String executeURL = url + "/session/" + id + "/execute";
          final HttpPost post = new HttpPost(executeURL);
          post.setEntity(new StringEntity(jsonString, "UTF8"));
          post.setHeader("Content-type", "application/json");
          final HttpEntity responseEntity = client.execute(post).getEntity();
          if (responseEntity != null) {
            try {
              final String responseString = EntityUtils.toString(responseEntity);
              // {"status":0,"value":{"ELEMENT":"1"},"sessionId":"8e982755-980f-4036-b3d1-c0e14e890273"}
              final String elementId = parser.parse(responseString)
                  .getAsJsonObject().get("value").getAsJsonObject().get("ELEMENT")
                  .getAsString();
              element = newElement(elementId);
            } catch (final Exception e) {
              e.printStackTrace();
            } finally {
              EntityUtils.consume(responseEntity);
            }
          }
        } catch (final Exception e) {
          e.printStackTrace();
        }
        return element;
      }
