Azure ARM DataFactory InvalidTemplate runAfter 属性无效；范围必须属于同一级别

Question

在这里记录我学到的东西，以防对其他人有帮助。我有一个实现 DataFactory 管道的 ARM 模板，它有一个奇怪的 InvalidTemplate 错误。我正在将我的模板简化为一个人为的简单模板，

    resources: [
    {
        "name": "blah",
            "type": "Microsoft.DataFactory/factories/pipelines",
            "apiVersion": "2018-06-01",
            "properties": {
                "activities": [
                {
                    "name": "Foo",
                    "type": "SetVariable",
                    "dependsOn": [],
                    "userProperties": [],
                    "typeProperties": {
                        "variableName": "hi",
                        "value": {
                            "value": "int(1)",
                            "type": "Expression"
                        }
                    }
                },
                {
                    "name": "CoolIf",
                    "type": "IfCondition",
                    "typeProperties": {
                        "expression": {
                            "value": "@bool(equals(variables('hi'), 1))",
                            "type": "Expression"
                        },
                        "ifTrueActivities": [
                            {
                                "name": "Blarg",
                                "type": "SetVariable",
                                "dependsOn": [{"activity": "Foo"}],
                                "userProperties": [],
                                "typeProperties": {
                                    "variableName": "okay",
                                    "value": {
                                        "value": "@string(1 + int(variables('hi')))",
                                        "type": "Expression"
                                    }
                                }
                            },
                        ],
                        "ifFalseActivities": []
                    }
                }
                ]
            }
    }
    ]

产生错误消息

ErrorCode=InvalidTemplate, ErrorMessage=The template validation
 failed: 'The 'runAfter' property of template action 'BlargScope'
 is not valid: the action 'FooScope' must belong to same level as
 action 'BlargScope'. Available actions on same level: ''

我在网上找不到好的答案。

经过一天的尝试和错误，我意识到您可以在 IfCondition 父级中放置 dependsOn ，因此下面，只需移动 dependsOn从子级 Blarg 到父级 CoolIf。然后它开始工作=)。

            "type": "Microsoft.DataFactory/factories/pipelines",

                        }
                    }
                },
                {
                    "name": "CoolIf",

                                "type": "SetVariable",
                                "dependsOn": [],
                                "userProperties": [],
                                "typeProperties": {

                                    }
                                }
                            },
                        ],
                        "ifFalseActivities": []
                    }
                }
                ]
            }
    }
    ]

现在回想起来，我觉得这很愚蠢，哈哈。
