I am trying to create a volume with terraform, but the error does not indicate any reason(s) why. I can create it using the web interface.

Code:

resource "digitalocean_volume" "vs001images" {
  region                  = "LON1"
  name                    = "vs001images"
  size                    = 2
  initial_filesystem_type = "ext4"
  description             = "Data volume for user and system images"
}

The error reported:

digitalocean_volume.vs001images: Creating...
  description:             "" => "Data volume for user and system images"
  droplet_ids.#:           "" => "<computed>"
  filesystem_label:        "" => "<computed>"
  filesystem_type:         "" => "<computed>"
  initial_filesystem_type: "" => "ext4"
  name:                    "" => "vs001images"
  region:                  "" => "LON1"
  size:                    "" => "2"

Error: Error applying plan:

1 error(s) occurred:

* digitalocean_volume.vs001images: 1 error(s) occurred:

I have seen that some other errors indicating that the region might not support this, but there are no signs here.
