  You can dynamically update the compression and ping schedule settings. However,
  you must re-include seeds or `proxy_address` in the settings update request.
  For example:
  
  [source,console]
  
negative.code:           "mode": null,
            "seeds": null,
            "skip_unavailable": null,
            "transport.compress": null
          }
        }
      }
