Key "name" not found for parameter reference

Just tried to generate my first client and hit this issue. I think using $ref for a parameter definition is pretty standard and looking at the spec doc it appears to be done correctly. Any ideas?

Here's what I think is the relevant snippet from the spec.

paths:
  /organizations/{org_id}/usage_export_job/{usage_export_job_id}:
    parameters:
      - $ref: '#/components/parameters/org_id'
      - $ref: '#/components/parameters/usage_export_job_id'

components:
  parameters:
    usage_export_job_id:
      name: usage_export_job_id
      description: An opaque identifier of a usage export job.
      example: e8235eed-f121-4ae3-9c72-2719d6572818
      in: path
      required: true
      schema:
        type: string
        format: uuid

Note: I'm using a YAML version of the spec but the original from CircleCI is in json format. The same error occurs using either format though.
