Inappropriate value for attribute "network_interface_id": string required

Answer 1

您需要为“ids”中的每个元素进行配置，因此它应该如下所示:

resource "azurerm_network_interface_backend_address_pool_association" "main" {
  count                 = var.node_count
  ip_configuration_name   = "Configuration-VMs-${count.index}"
  network_interface_id = element(module.linuxservers.vm_ids, count.index)
  backend_address_pool_id = azurerm_lb_backend_address_pool.main.id
}

我不确定这里的语法element(module.linuxservers.vm_ids, count.index)，因为我不知道这个输出是在哪里定义的(也许我是瞎子)。但这正是您所需要的。
