Json模式oneOf无法按预期工作

Question

我正在尝试创建一个模式，该模式允许有效负载或有效负载转换，但不能同时允许两者。如果payloadTransition存在，则stateMaps必须存在，但是如果payload存在，则stateMaps不存在。这是我的json模式：

  "$id": "mqttsources-op",
  "constructor": {

                            "description": "The payload it transitions from",

                          }

                ],

                  { "required": [ {"$ref": "#/eventMaps/payloadTransition"},

                  },
                  { "required": [ {"$ref": "#/eventMaps/payload"}],
                    "not": { "required": [ {"$ref": "#/stateMaps"}]}
                  }
                ]

        },
        "required": [ "host", "modelMaps"],
        "additionalProperties": false
      }
    }
  }
}

总体上来说，我对json还是很陌生，对oneOf和复杂的模式（如我当前所需的模式）来说，还是很新的。我正在使用的输入文件如下所示，它会验证不应该使用的架构：

{
  "name": "MQTT-DPS",
  "host": "1.2.3.4",
  "port": 1883,
  "modelMaps": [
    {
      "topic": "joelsigurd/feeds/pir",
      "service": "portalcomp",
      "interface": "doormonitor-op-obs",
      "model": "doorPositionModel",
      "defaultState": "isUnknown",
      "stateMaps": [
        {
          "payload": "0",
          "state": "isClosed"
        },
        {
          "payload": "1",
          "state": "isOpen"
        }
      ],
      "eventMaps": [
        {
          "payloadTransition": {
            "from": "0",
            "to": "1"
          },
          "payload": "1",
          "event": "doorOpenedEvent"
        },
        {
          "payloadTransition": {
            "from": "1",
            "to": "0"
          },
          "event": "doorClosedEvent"
        }
      ]
    }
  ]
}

我在做什么错了？
