Debug Output

$ terraform workspace new test
NotFound: Not Found
        status code: 404, request id: , host id:

Expected Behavior

(From Terraform Docs)
key - (Required) The path to the state file inside the bucket. When using a non-default workspace, the state path will be /workspace_key_prefix/workspace_name/key

A new object should be created: terraform-state/test/terraform.tfstate

Actual Behavior

See debug output - no new statefile created

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. Setup OPC provider and remote state backend
2. terraform init
3. terraform workspace new test

Important Factoids

Remote state works perfectly fine in default workspace.

OCI-C does not allow sub directories within a bucket, so is it even possible for OCI-C object storage to support multiple workspaces?
