I am running below code , getting argument not expected here ,but the arguments are there in the terraform document . Please advise. variables.tf file

      type = list(object(
        {

You forgot about content. it should be:

  dynamic "frontend_ip_configuration" {
    for_each                      = { for fip in each.value.frontend_ip_config : fip.frontend_ip_name => fip }

    content { 
      name                          = frontend_ip_configuration.value.frontend_ip_name
      subnet_id                     = data.azurerm_subnet.subnet[frontend_ip_configuration.value.lb_name].id  
      private_ip_address            = frontend_ip_configuration.value.private_ip_address
      private_ip_address_allocation = frontend_ip_configuration.value.private_ip_address == null ? "Dynamic" : "Static"
   }
