有几个 stackoverflow 帖子有类似的问题，但没有一个有授权错误问题。

我在Azure China上使用带有 eventthub 触发器的 C# 代码运行 Azure 函数时遇到问题。相同的代码在 Azure 全局上运行良好。

触发器的连接字符串是正确的，我用Listen和Manage权限尝试过，同样的问题。

任何帮助表示赞赏。

这里是完整的错误信息：

Microsoft.Azure.WebJobs.Host.Listeners.FunctionListenerException: The listener for function 'FilterFunctionEventhubTrigger' was unable to start.

这是我的csproj文件。

问题是 VNet 中缺少子网。
