Failed to get existing Workspace with Openstack swift backend

Terraform
1

Hi!
I’m trying to use ‘swift’ as a backend for terraform remote state, but actually having troubles to initialize it.

backend "swift" {
  container = "terraform-state"
  archive_container = "terraform-state-archive"
  cloud = "openstack"
}

but got this error:

Error: Failed to get existing workspaces: Expected HTTP response code [201 202 204] when accessing [PUT https://swift.cloud.garr.it/swift/v1/terraform-state], but got 412 instead
