使用Azure CLI创建Data Factory触发器时遇InvalidTriggerType错误求助

问题重现 #

执行以下Azure CLI命令创建触发器：

az datafactory trigger create --factory-name test-factory-01 --resource-group ITS-TEST-RG --properties trigger.json --name stg2trans_accountspayable_erp_ap_trigger

使用的trigger.json内容：

{"properties": {"annotations": [],"runtimeState": "Stopped","pipeline": {"pipelineReference": {"referenceName": "pipeline1_wf","type": "PipelineReference"}},"type": "TumblingWindowTrigger","typeProperties": {"frequency": "Hour","interval": 24,"startTime": "2022-03-24T06:00:00Z","delay": "00:00:00","maxConcurrency": 50,"retryPolicy": {"intervalInSeconds": 30},"dependsOn": []}}}"

运行后抛出错误：

(InvalidTriggerType) Invalid trigger type: null

问题原因 #

触发器JSON定义中type字段的位置错误，它被放在了properties对象内部。Azure Data Factory要求type是顶级属性，不属于properties的子属性，CLI解析时无法识别正确类型，因此返回null错误。

解决方案 #

修正trigger.json，将type字段移至根层级，调整后的内容如下：

{
  "type": "TumblingWindowTrigger",
  "properties": {
    "annotations": [],
    "runtimeState": "Stopped",
    "pipeline": {
      "pipelineReference": {
        "referenceName": "pipeline1_wf",
        "type": "PipelineReference"
      }
    },
    "typeProperties": {
      "frequency": "Hour",
      "interval": 24,
      "startTime": "2022-03-24T06:00:00Z",
      "delay": "00:00:00",
      "maxConcurrency": 50,
      "retryPolicy": {
        "intervalInSeconds": 30
      },
      "dependsOn": []
    }
  }
}

验证步骤 #

1. 保存修正后的trigger.json文件
2. 重新执行原Azure CLI命令
3. 若执行成功，可通过以下命令验证触发器状态：

az datafactory trigger show --factory-name test-factory-01 --resource-group ITS-TEST-RG --name stg2trans_accountspayable_erp_ap_trigger
