Terraform / scaleway_vpc_gateway_network / internal server error

[cm-intranet]

Hello,
I am unable to create a VPC/Public Gateway/Network with Terraform.
Terraform init & plan are OK, but when i apply the code it ends with a "error 500 Internal Server Error".

Here is what i do:

Terraform Version

Terraform v1.7.4
on linux_amd64

• provider registry.terraform.io/scaleway/scaleway v2.37.0

Affected Resource(s)

"scaleway_vpc_gateway_network"

Terraform Configuration Files

I just copy/paste code from this scaleway terraform example: https://registry.terraform.io/providers/scaleway/scaleway/latest/docs/resources/vpc_public_gateway_pat_rule

With this configuration:

cat terraform.tf
terraform {
required_providers {
scaleway = {
source = "scaleway/scaleway"
version = ">= 2.37"
}
}
required_version = ">= 0.13"
}

cat provider.tf
provider "scaleway" {
zone = "fr-par-2"
region = "fr-par"
}

Debug Output

Expected Behavior

A public gateway attached to a private network should have been created.

Actual Behavior

Here, after applying the plan, i have ''4'' VPC created and one with a private network attached (!)
I also have a public gateway, but not attached to the private network and in "IPAM" mode, even if a DHCP Id has been provided.

Steps to Reproduce

1. terraform apply

Hi,

I have the exact same issues as @cm-intranet:

• Four VPCs get created (never asked for four)
• Then at the end of the terraform apply, I get an error 500
• Gateway shows "IPAM" mode instead of DHCP in the Scaleway web UI

Additionally, when destroying the deployment (terraform destroy), the four created VPCs are not destroyed ⚠️ although the command completes successfully, without warning or error.

I copy/pasted the code from How to use Scaleway VPC SSH Bastion config. Here's my complete Terraform code:

terraform {
  required_version = ">= 1.7"

  required_providers {
    scaleway = {
      source = "scaleway/scaleway"
      version = "~> 2.37"
    }
  }
}

provider "scaleway" {
    zone = "fr-par-1"
}

variable "machine_count" {
  description = "Number of virtual machines in private network"
  default = 3
}

# SCALEWAY VPC PRIVATE NETWORK
resource scaleway_vpc_private_network "pn" {
  name = "myprivatenetwork"
}

# SCALEWAY VPC VIRTUAL MACHINES
resource scaleway_instance_server "servers" {
  count    = var.machine_count
  name     = "machine${count.index}"
  image = "ubuntu_focal"
  type  = "DEV1-S"
}

# SCALEWAY INSTANCES PRIVATE NETWORK CONNECTION
resource scaleway_instance_private_nic "nic" {
  count              = length(scaleway_instance_server.servers)
  private_network_id = scaleway_vpc_private_network.pn.id
  server_id          = scaleway_instance_server.servers[count.index].id
}

# SCALEWAY PUBLIC GATEWAY IP
resource scaleway_vpc_public_gateway_ip "pgw_ip" {
}

resource scaleway_vpc_public_gateway "pgw" {
  type = "VPC-GW-S"
  bastion_enabled = true
  ip_id = scaleway_vpc_public_gateway_ip.pgw_ip.id
}

resource scaleway_vpc_public_gateway_dhcp "dhcp" {
  subnet = "192.168.1.0/24"
  dns_local_name = scaleway_vpc_private_network.pn.name
}

resource scaleway_vpc_gateway_network "gn" {
  gateway_id          = scaleway_vpc_public_gateway.pgw.id
  private_network_id  = scaleway_vpc_private_network.pn.id
  dhcp_id             = scaleway_vpc_public_gateway_dhcp.dhcp.id
  enable_dhcp         = true
}

I'm creating a support ticket to report this as well as it seems to be a critical issue.

Customer support told me ~45mn ago that they are "immediately passing on this critical flaw report to our product team so that they can investigate it and patch our problem source code".

Hello,

On friday, I noticed that behaviour also.

I used version 2.36.0 of scaleway provider and version 1.6.6 of terraform.

Updated today to version 2.38.0 of provider, nothing changed.

On Wednesday 6th, all worked fine

Hello, this is not an issue with terraform provider but with the API.
It is fixed so I will close this for now.
