It is not possible to add a new private lan to the dataplatform cluster via Terraform

[FLST-btelligent]

Description

I adjusted the terraform code to add a newly created lan to the already existing dataplatform cluster and I found two different issues:

1. It is not possible to add a private lan to the cluster without routes (In the documentation it is marked as optional): Error: an error occured while updating a Dataplatform Cluster: 422 Unprocessable Entity: {"httpStatus":422,"messages":[{"errorCode":"dsaas-400","message":"'Value is not nullable' caused by field /properties/lans/0/routes"}]}
2. It is not possible to add a private lan to an existing cluster add all. Every time I try to add the private lan, the terraform pipeline reaches the timeout.

Here is the code for my Cluster:

data "ionoscloud_private_crossconnect" "main" {
name = "shared-xconn"
}

resource "ionoscloud_lan" "main" {
name = "lan"
datacenter_id = module.ionos_dc.datacenter_id
public = false
ipv6_cidr_block = "AUTO"
pcc = data.ionoscloud_private_crossconnect.main.id
}

resource "ionoscloud_dataplatform_cluster" "main" {
datacenter_id = var.datacenter_id
name = "sdp-cluster"

version = var.stackable_version

lans {
lan_id = ionoscloud_lan.main.id
dhcp = true
routes {
network = ionoscloud_lan.main.ipv6_cidr_block
gateway = "217.160.216.1"
}
}

maintenance_window {
day_of_the_week = "Sunday"
time = "09:00:00"
}
}

Expected behavior

It should create the lan and add it even if there are no routes defined.

Environment

v1.5.7

v6.4.15

Hello! Sorry for the late response, we had some days off for Easter.

Related to the first point from the issue, I will take a look, this shouldn't happen, the routes is marked as optional because it is optional indeed, so the creation without routes should work.

Related to the second point, this is a known issue, please read Known Issues section https://github.com/ionos-cloud/terraform-provider-ionoscloud/releases/tag/v6.4.15 where a workaround is presented.

Thank you!
