Création d'un réseau privé avec Terraform

Bonjour,

J'essaie de créer un réseau privé via terraform et d'y ajouter une instance. Le réseau et le sous-réseau ce créent correctement mais j'ai une erreur au moment de la création de l'instance.

Voilà mon fichier de configuration:

```
# main.tf

# Version terraform: Terraform v1.0.11

terraform {
required_providers {
openstack = {
source = "terraform-provider-openstack/openstack"
version = "1.45.0"
}

ovh = {
source = "ovh/ovh"
version = "0.18.1"
}
}
}

provider "openstack" {
auth_url = "https://auth.cloud.ovh.net/v3/"
domain_name = "default" # Always "default" for OVHcloud
alias = "ovh"
tenant_id = "..."
}

provider "ovh" {
alias = "ovh"
endpoint = "ovh-eu"
application_key = "..."
application_secret = "..."
consumer_key = "..."
}

resource "ovh_cloud_project_network_private" "hadb-pn" {
provider = ovh.ovh
service_name = "..."
name = "pn-hadb"
regions = var.ovh_regions
vlan_id = 168
}

resource "ovh_cloud_project_network_private_subnet" "hadb-subnet" {
provider = ovh.ovh
service_name = "..."
network_id = ovh_cloud_project_network_private.hadb-pn.id
start = "10.42.0.1"
end = "10.42.0.100"
network = "10.42.0.0/24"
region = element(var.ovh_regions, 0)
no_gateway = true
}

module "ovh" {
source = "./modules/ovh"

providers = {
openstack = openstack.ovh
}

count = length(var.ovh_regions)

database_volume_size = var.database_volume_size
instance_type = "s1-2"
private_network_ip = "10.42.0.${count.index + 1}"
private_network_name = ovh_cloud_project_network_private.hadb-pn.name
region = element(var.ovh_regions, count.index)
ssh_key_path = var.ssh_key_path
ssh_key_name = var.ssh_key_name
subnet_id = ovh_cloud_project_network_private_subnet.hadb-subnet.id
}

# modules/ovh/main.tf

resource "openstack_compute_instance_v2" "ha-db" {
name = "ha-db"
image_name = "Ubuntu 18.04"
flavor_name = var.instance_type
key_pair = openstack_compute_keypair_v2.keypair.name
security_groups = [openstack_networking_secgroup_v2.ha-db_sg.name]
region = var.region

network {
name = "Ext-Net"
}

network {
name = var.private_network_name
fixed_ip_v4 = var.private_network_ip
}
}
```

Voilà l'erreur:
