userPeerNetworkCidrs cannot convert interface

What happened?

Plugin crashes 🤷

What did you expect to happen?

Plugin doesn't crash 😄

What else do we need to know?

  peer_cloud_account      = var.project_id
  peer_vpc                = "redacted"

  user_peer_network_cidrs = [var.cluster_subnet_ip_range]
  vpc_id                  = aiven_project_vpc.this.id
}

# aiven_transit_gateway_vpc_attachment.redacted will be created
  + resource "aiven_transit_gateway_vpc_attachment" "redacted" {
      + id                      = (known after apply)
