nohup. Why doesn't writing to a file with fwrite work?

Question

Node.js

Hello. Can you please tell me why writing to a file does not work when calling a file through nohup (nohup forever start /var/www/sitename/server.js)?

fs.readFile(this.filename, "utf-8", (err, data) => {
    let new_content = `${data}\n${text}`;

    fs.writeFile(this.filename, new_content);
  });
