Bluemix IoT Foundation Starter给出错误：与服务器的连接丢失

标签： ibm-cloud iot

我正在尝试Bluemix中的物联网基础入门样板。以下是我要遵循的步骤：

  1. 使用样板
    2. 创建新应用
  2. 应用程序启动后，我会转到URL并查看NodeRED主页
  3. 我点击按钮将我带到NodeRED编辑器
  4. 在另一个浏览器窗口中，我在此处提供了IoT传感器：https://quickstart.internetofthings.ibmcloud.com/iotsensor/启动并运行
  5. 我使用IoT传感器的地址配置“IoT App In Node”。我删除了“：”并将字母设为小写。
    1. 当我在NodeRED编辑器中单击Deploy时，我看到以下错误：“错误：丢失与服务器的连接”

    6. 在第2步之后，我已在日志中看到这些错误：

    在错误发生后的第5步之后，我看到以下错误：

    现在，如果我重新启动应用程序，一切正常。但是我每次都可以通过以下步骤一致地重新创建上述场景：

    1. 从样板创建新应用
    2. 转到NodeRED编辑器
    3. 配置IoT in-node
    4. 部署
    5. 得到错误
    6. 停止并启动运行时
    7. 一切正常

      8. 需要帮助弄清楚为什么会发生这种情况以及如何预防。

已经在Bluemix的npmjs和Internet of Things Foundation Starter样板中上传了一个永久修复程序，它解决了这个问题。
