The same Discord bot command on VPS does not work, although everything works on the computer (Discord.JS) How to solve?

Question

Node.js

Here is the code:

The code

const fs = require('fs');
const format = require('node.date-time');

const cfg = {"token": "Токен бота", "prefix": "=","welcomehookid":"ID вебхука", "welcomehooktoken":"Токен вебхука",}
const token = cfg.token;
const prefix = cfg.prefix;
const Discord = require('discord.js');
const { stringify } = require('querystring');
const bot = new Discord.Client();
const welcomehook = new Discord.WebhookClient(cfg.welcomehookid, cfg.welcomehooktoken);
const newshook = new Discord.WebhookClient("ID вебхука", "Токен вебхука");
const newsForHook = news.newsToPublish;
const langMessages = {

  });
};

I have this code both on my computer (everything works on it) and on the VPS (only the clear bot command does not work there (this command deletes all messages in the text channel))

On the VPS, when using the clear bot command, it gives the following error:

Answer 1

You have node version 10 or lower on the server. Update.
Array.prototype.flatMap() appeared in Node.js v11.0.0
