  # What is here:
  # 1.
  #     https://grafana.com/docs/grafana/latest/http_api/dashboard/
  #     Wrap the file in a structure that allows you to create/update it via the API.
  # 2.
  #     .dashboard.id property is set to null to avoid "Dashboard not found" error.
  #     https://github.com/hagen1778/grafana-import-export/issues/10
  #     'sed' solution proposed in the workaround is incorrect, because .dasboard.id property may not exist.
