After the first error if another Terraform apply is attempted it will fail again but with another error saying that a policy with that name already exists.

Error: error creating ACL policy: Unexpected response code: 500 (rpc error making call: Invalid Policy: A Policy with Name "consul-test" already exists)

1. terraform apply

Important Factoids

Are there anything atypical about your accounts that we should know? For example: Running in EC2 Classic? Custom version of OpenStack? Tight ACLs?

I have ACLs enabled and am currently using the Bootstrap Token (Global Management) token.
