Как решить ошибку сервера Server error: res is not defined?

Локально проект запускался нормально, когда выложил на хостинг выводится ошибка при старте node.js server:

Server error: res is not defined

вроде запускается нормально сначала, но секунд через 5 просто завершается

[altairre.ae/server (14)] [altair@business95 server]$ npm run start
