Error when creating pipeline: Invalid address to set

Terraform v0.11.13

Issue

When attempting to create a pipeline with the following code:

provider "buildkite" {
  api_token = "${var.buildkite_token}"
  organization = "${var.buildkite_organization}"
}

resource "buildkite_pipeline" "pipeline" {
  name = "${var.pipeline_name}"
  repository = "${var.pipeline_repo_url}"

  step = "${var.pipeline_steps}"
}

I receive the following error:

Error: Error refreshing state: 1 error(s) occurred:

* buildkite_pipeline.pipeline: 1 error(s) occurred:

Any idea what can be done to fix this?
