无法在 IoT Agent Fiware 中配置执行器

问题描述

我正在使用以下 python 代码创建服务组

import json
import requests

url = 'http://localhost:4041/iot/services'
headers = {'Content-Type': "application/json",'fiware-service': "openiot",'fiware-servicepath': "/mtp"}

data = {
 "services": [
   {
     "apikey":      "456dgffdg56465dfg","cbroker":     "http://orion:1026","entity_type": "Door",#resource attribute is left blank since HTTP communication is not being used
     "resource":    ""
   }
 ]
}
res = requests.post(url,json=data,headers=headers)
#print(res.status_code)

if res.status_code == 201:
    print("Created")

elif res.status_code == 409:
    print("A resource cannot be created because it already exists")

else:
    print (res.raise_for_status())

但是在尝试配置执行器时，我收到错误请求 400 错误，代码如下：

import json
import requests

url = 'http://localhost:4041/iot/devices'
headers = {'Content-Type': "application/json",'fiware-servicepath': "/mtp"}

data = {
 "devices": [
    {
      "device_id": "door003","entity_name": "urn:ngsi-ld:Door:door003","protocol": "PDI-IoTA-UltraLight","transport": "MQTT","commands": [
        {"name": "unlock","type": "command"},{"name": "open",{"name": "close",{"name": "lock","type": "command"}
       ],"attributes": [
        {"object_id": "s","name": "state","type":"Text"}
       ]
    }
  ]
}

res = requests.post(url,headers=headers)
#print(res.status_code)

if res.status_code == 201:
    print("Created")

elif res.status_code == 409:
    print("Entity cannot be created because it already exists")

else:
    print (res.raise_for_status())

这是我在控制台中收到的错误消息。

奇怪的是，如果从有效负载中删除命令，则设备配置工作正常。尝试配置执行器（不是传感器）时我做错了什么？

物联网代理版本：

{"libVersion":"2.14.0-next","port":"4041","baseRoot":"/","version":"1.15.0-next"}

猎户座版本：

{
"orion" : {
  "version" : "2.2.0","uptime" : "0 d,0 h,59 m,18 s","git_hash" : "5a46a70de9e0b809cce1a1b7295027eea0aa757f","compile_time" : "Thu Feb 21 10:28:42 UTC 2019","compiled_by" : "root","compiled_in" : "442fc4d225cf","release_date" : "Thu Feb 21 10:28:42 UTC 2019","doc" : "https://fiware-orion.rtfd.io/en/2.2.0/"
}
}

我的 docker-compose 文件如下所示：

iot-agent:

    container_name: iot-agent
    restart: unless-stopped
