Please ensure that your oath keeper/config/config.yaml looks like this:

authorizers:
  allow:
    enabled: true
  remote_json:
    enabled: true
    config:
      remote: http://keto-api:4456/check
      forward_response_headers_to_upstream: []
      payload: |
        {
          "subject": "{{ print .Subject }}",
          "resource": "{{ printIndex .MatchContext.RegexpCaptureGroups 0 }}"
        }

Notice forward_response_headers_to_upstream: [] which you are missing.
