【问题描述】：

我正在尝试为 Thingsboard IoT Gateway 设置 REST 连接器，并在初始化时遇到一些错误。我的 rest.json 配置是：

{
  "host": "127.0.0.1",
  "port": "5000",
  "SSL": false,
  "mapping": [
    {
      "endpoint": "/sizerdata",
      "HTTPMethods": [
        "POST"
      ],
      "security": {
        "type": "anonymous"
      },
      "converter": {
        "type": "json",
        "deviceNameExpression": "Sizer ${name}",
        "deviceTypeExpression": "default",
        "attributes": [
          {
            "type": "string",
            "key": "serialNumber",
            "value": "${serialNumber}"
          }
        ],
        "timeseries": [
          {
            "type": "integer",
            "key": "cupfill",
            "value": "${cupfill}"
          },
          {
            "type": "integer",
            "key": "packsPerHour",
            "value": "${packsPerHour}"
          },
          {
            "type": "integer",
            "key": "totalFruitPerMinute",
            "value": "${totalFruitPerMinute}"
          }
        ]
      }
    }
  ]
}

当我启动 thingsboard-gateway 服务时，我在日志中收到以下错误：

""2021-12-29 13:09:07" - |ERROR| - [rest_connector.py] - rest_connector - run - 152 - web.Application instance initialized with different loop"

我已经在 Ubuntu 安装和 Docker 容器上尝试过这个，我得到了相同的结果。关于为什么这不起作用的任何想法？

【解决方案1】：

这是 aiohttp 的问题，它已经在 master 分支中修复。您可以使用网关存储库主分支中的版本或等待下一个版本。

感谢@Zbeacon，由 master 分支构建，一切正常。
