添加嵌套的 OPC-UA 变量结果 "String cannot be coerced to a nodeId"

Question

错误：无法将字符串强制转换为 nodeId

你好，我正忙于使用 opcua iotagent 代理在 Orion Broker 和带有 OPC-UA 服务器的 PLC 之间建立连接。我设法设置了所有部分并且我能够接收（测试）数据，但是我无法按照教程使用 json 文件向 Orion-Broker 添加实体：

curl http://localhost:4001/iot/devices      -H "fiware-service: plcservice"      -H "fiware-servicepath: /demo"      -H "Content-Type: application/json"      -d @add_device.json

预期结果是使用提供的数据将实体添加到 OrionBroker，但这只会导致错误消息：

{"name":"Error","message":"String cannot be coerced to a nodeId : ns*4:s*MAIN.mainVar"}

疑似错误

iotagent 是否可能无法很好地与嵌套变量一起使用？

采取的步骤

双重检查 OPC 数据的可用性：
- OPC数据每秒变化，可以在Broker日志中看到
降低了设置的复杂性以仅包括 Broker 和 IOT-agent

补充信息：

add_device.json 文件:

{ 
"devices": [
    {
        "device_id": "plc1",
        "entity_name": "PLC1",
        "entity_type": "plc",
        "attributes": [
            
            {
                "object_id": "ns*4:s*MAIN.mainVar",
                "name": "main",
                "type": "Number"
            }
        ],
        "lazy": [
        ],
        "commands" : []
  }
]

}

我是 iotagent-opcua 存储库的维护者之一，我们已经识别并修复了您所解决的错误，请将您的代理更新到最新版本 (1.4.0)

如果您从未听说过，从 1.3.8 开始，我们引入了一个名为“relaxTemplateValidation”的新配置属性，它允许您使用以前禁止使用的字符（例如 = 和 ; ）。我建议你看看它提供的配置示例。
