DeployIfnotexists azure 策略失败并出现错误

Question

我是 azure 策略的新手，我正在尝试为存储帐户编写 deployifnotexists 策略，该策略将为 300 天的容器启用时间点还原。它在部署时出错，错误提示 HttpResourceNotFound 和随机 http 请求 url。我想知道该政策是否正确，这是我创建的我正在使用的代码：

如果要为容器启用时间点恢复，类型应为Microsoft.Storage/storageAccounts/blobServices。 Azure ARM 模板不提供类型Microsoft.Storage/storageAccounts/blobServices/restorePolicy。

例如

{
            "name": "[concat(parameters('storageAccountName'), '/default')]",
            "type": "Microsoft.Storage/storageAccounts/blobServices",
            "apiVersion": "2019-06-01",
            "properties": {
                "restorePolicy": {
                    "enabled": "[parameters('isContainerRestoreEnabled')]",
                    "days": "[parameters('containerRestorePeriodDays')]"
                },
                "deleteRetentionPolicy": {
                    "enabled": "[parameters('isBlobSoftDeleteEnabled')]",
                    "days": "[parameters('blobSoftDeleteRetentionDays')]"
                },
                "containerDeleteRetentionPolicy": {
                    "enabled": "[parameters('isContainerSoftDeleteEnabled')]"
                },
                "changeFeed": {
                    "enabled": "[parameters('changeFeed')]"
                },
                "isVersioningEnabled": "[parameters('isVersioningEnabled')]"
            },
            "dependsOn": [
                "[concat('Microsoft.Storage/storageAccounts/', parameters('storageAccountName'))]"
            ]
        }
