如果你检查azurerm_lb_backend_address_pool的文档，你会发现它没有resource_group_name参数，所以它应该是：

resource "azurerm_lb_backend_address_pool" "internal_lb_controlplane_pool_v4" {
  count = var.use_ipv4 ? 1 : 0
  loadbalancer_id     = azurerm_lb.internal.id
  name                = var.cluster_id
}

由于语法错误导致问题。不需要resource_group_name。

resource "azurerm_lb_backend_address_pool" "example" {
  loadbalancer_id = azurerm_lb.example.id
  name            = "BackEndAddressPool"
}

这是代码reference并复制了相同的代码
主要任务如下：

data "azurerm_client_config" "current" {}

resource "azurerm_resource_group" "example" {
  name     = "********"
  location = "West Europe"
}
resource "azurerm_public_ip" "example" {
  name                = "swarnaPublicIPForLB"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  allocation_method   = "Static"
}

resource "azurerm_lb" "example" {
  name                = "swarnaTestLoadBalancer"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name

  frontend_ip_configuration {
    name                 = "swanraPublicIPAddress"
    public_ip_address_id = azurerm_public_ip.example.id
  }
}

resource "azurerm_lb_backend_address_pool" "example" {
  loadbalancer_id = azurerm_lb.example.id
  name            = "BackEndAddressPool"
}
