如何处理firebase库异常？

由于firebase-node.js库中的异常，我的Nodejs服务器崩溃了！

var thermostateTree = nestAccounts[self.mac].firebaseClient.child('devices').child('thermostats').child(self.id);  

var callback = function(err){
if (err)
  logger.info('[%s] [Nest] [setTargetTemperature] failed to set target temperature. ', self.mac);
else
  logger.info('[%s] [Nest] [setTargetTemperature] target temperature changed', self.mac);
};

thermostateTree.update({
 'target_temperature_high_f' : max_temperature,
 'target_temperature_low_f' : min_temperature
}, callback);

我该如何处理以下异常？
