code: function onFailure(err) {
            onTimelyResponse(spec.code);
  
            logError(`Server call for ${spec.code} failed: ${err}. Continuing without bids.`);
            onResponse();
          }
docs: If the server responds with an error, there's not much we can do. Log it, and make sure to call onResponse() so that we're one step closer to calling done().
