I downloaded the sources of the trade bot on node js, after installation an error appeared, how can I solve it, and how do I set up such a bot in general?

Question

Node.js

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 got such an error
Who has experience in setting up or creating trade bots, please help, there is almost no information on the Internet about how to set up such bots.

Try to specify a function as the third parameter of fs callback, as indicated here . The line where to replace is indicated in the error

fs.writeFile("hello.txt", "Hello мир!", function(error){
 
    if(error) throw error; // если возникла ошибка
    console.log("Асинхронная запись файла завершена. Содержимое файла:");
    let data = fs.readFileSync("hello.txt", "utf8");
    console.log(data);  // выводим считанные данные
});
