Postgresql 尝试在azure云提供商上创建专用链接时出现问题

我正在尝试开发terraform脚本，在Azure上创建虚拟机，并使用专用链接将其连接到Azure Postgresql实例。我总是会遇到这样的错误：

Error: creating Private Endpoint "n4gx6y-endpoint" (Resource Group "PGSQLResourceGroup"): 
network.PrivateEndpointsClient#CreateOrUpdate: 
Failure sending request: StatusCode=400 -- Original Error: 
Code="IncorrectPrivateLinkServiceConnectionGroupId" 
Message="Call to Microsoft.DBforPostgreSQL/servers failed.

  on main.tf line 68, in resource "azurerm_private_endpoint" "example":

这是github回购协议，脚本相同，一个用于Postgres，一个用于Mariadb。该错误仅在Postgres中出现

问题实际上与脚本的这一部分有关：
