Error when launching the trade offer bot steam, who is ready to help with the setup?

Question

JavaScript

I downloaded the node js trade bot sources from here -> https://github.com/alex7kom/node-steam-tradeoffers <- unpacked it into a prepared folder in the domains Open Server. Since I only needed a bot that sends a trade to another person, I decided to use the ready-made code from examples/offerbot.js I downloaded additional node-steam, steam-weblogon, and steam-web-api-key I entered the data, I received an email , but after the next launch I received such an error
Who can help set up the bot write. I can give you a small reward.
