【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。
为了实现这一点，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“订阅”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 是一个有效的工件位置 sas 令牌。 （我假设，它看起来是正确的）
我了解此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，我不确定为什么它无法下载部署内容...
更新/编辑： 值得注意的是，该版本使用的是经典 Azure 发布管道。并且在发布过程中出现错误。
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，所以至少我知道在哪里错误来自。仍在调查导致这种误读的原因...
【问题讨论】：

据我了解，您有一个自定义主题。现在您要为主题创建订阅，订阅将触发 Azure 函数。对吗？
-
@JimXu 完全正确。一旦我将父/部署模板中的新条目放在资源列表的底部，奇怪的订阅错误实际上就解决了。我不喜欢我在最后注入了一个新资源，我猜。还是很奇怪。但是我仍在处理无效的内容链接错误。
