Debug Output

The relevant bit of log is:

{
  "name":"test",
  "dynamic_ip_required":false,
  "commercial_type":"DEV1-M",
  "image":"291b1402-9650-45a9-8928-295634438dff",
  "volumes": {
    "0":{"boot":false,"size":20000000000,"volume_type":"sbs_volume"},
    "1":{"id":"c73da032-cbe8-4345-a83d-4392d2928ea1","volume_type":"sbs_volume"}
  },
  "public_ips":["XXXXXX-1325-XXXX-8b3f-XXXXXX","XXXXXX-7cb1-XXXX-bb12-XXXXXXXX"],
  "boot_type":"local",
  "project":"XXXXXX-46e1-XXXX-8dc1-XXXXXX"
}

{"message": "Cannot create a volume of type sbs_volume from a base of type unified", "type": "precondition_failed"}

Expected Behavior

It is possible to create an instance with a disk backed by an SBS volume.

This is perfectly fine when using the web console.

Actual Behavior

The "apply" step fails as described above.

Steps to Reproduce

1. terraform apply

Important Factoids

The documentation for scaleway_instance_server states that root_volume.type can be sbs_volume, l_ssd or b_ssd.
However, b_ssd is not accepted, and sbs_volume does not work.
