azure - 尝试为 Azure 函数部署事件网格订阅时出现 InvalidResourceNamespace 错误

问题描述

我有一个现有的事件网格主题，并希望使用现有的 Azure 函数端点向它添加一个事件订阅。

为此，我使用了链接模板。ARM 模板验证通过，但部署失败，出现一个非常奇怪的错误：

"InvalidResourceNamespace: "资源命名空间 'subscriptions' 无效。（代码：InvalidResourceNamespace）”

这是原始错误：

{
  "code": "DeploymentFailed",
  "message": "At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.",
  "details": [
    {
      "code": "InvalidContentLink",
      "message": "Unable to download deployment content from 'https://storagearmtpl.blob.core.windows.net/arm-tpl-service-cd-11111-artifacts/nestedtemplates/eventGridSubscriptionTemplate.json?sv=sasartifactsstring'. The tracking Id is '11111111'. Please see https://aka.ms/arm-deploy for usage details."
    },
    {
      "code": "InvalidResourceNamespace",
      "message": "The resource namespace 'subscriptions' is invalid."
    }
  ]
}

sasartifactsstring有效的工件位置 sas 令牌在哪里。（我假设，它看起来是正确的）

我知道这个错误源于模板中资源的“类型”无效，但正如您在下面看到的，它只是Microsoft.EventGrid/topics/providers/eventSubscriptions.

真的不确定我在这里做错了什么。值得注意的是，第一个错误也很烦人，我不确定为什么它不能下载部署内容......

更新/编辑： 值得注意的是，该版本使用的是经典 Azure 发布管道。并且在发布期间出现错误。

查看资源组的部署日志，我能够看到部署正在尝试部署无效资源，类型以“subscriptions/.....”开头，所以至少我知道错误出在哪里从。仍在调查导致这种误读的原因......

解决方案

奇怪的“订阅”错误的原因是我在我的部署（父）ARM 模板的资源列表中插入了一个新资源，但不是在列表的末尾。

一旦我将引用新事件网格订阅的部署资源放在资源列表的末尾，错误就没有出现。

天蓝色部署.json

resources: [
  {all other existing deployment resources ....},
  {
     "name": "functionsubscription"
     "type": "Microsoft.Resources/deployments",
     "apiVersion": "2017-05-10"
     "resourceGroup": "[parameters('topicResourceGroupName')]",
      "dependsOn": [ ],
      "properties": {
        "mode": "Incremental",
        "templateLink": {
          "uri": "[concat(parameters('_artifactsLocation'), '/', variables('templateFolder'), '/', variables('subscriptionTemplateFileName'), parameters('_artifactsLocationSasToken'))]",
          "contentVersion": "1.0.0.0"
        },
        "parameters": {
          "subscriptionName": {
            "value": "FunctionSubscription"
          },
          "topicName": {
            "value": "[parameters('topicName')]" 
          },
          "functionResourceGroupName": {
            "value": "[parameters('functionResourceGroupName')]"
          },
          "functionAppName": {
            "value": "[parameters('functionAppName')]"
          },
          "topicResourceGroupName": {
            "value": "[parameters('topicResourceGroupName')]"
          },
          "subscriptionId": {
            "value": "[parameters('subscriptionId')]"
          }
        }
      }
    }
]

但是，我仍在处理 InvalidContentLink 错误，问题的主要问题已经解决。
