TypeError: Cannot read properties of null (reading 'map')

Question

I am trying to get my Etherscan Verified Contract Scraper that forwards new Verified Contracts to a specific Discord channel working and have run into issues.

Here is the code--

const Discord = require("discord.js");
const fetch = require("node-fetch");
const config = require("./config.json");
const { Client, GatewayIntentBits } = require('discord.js');

const client = new Discord.Client({
  intents: [
    GatewayIntentBits.Guilds,
    GatewayIntentBits.GuildMessages,
  ]
})

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`);
});

// Replace CHANNEL_ID with the ID of the channel you want to post in
const channel = client.channels.cache.get('CHANNELID');

// Scrape new verified contracts from Etherscan every minute
setInterval(async () => {
  const response = await fetch('https://etherscan.io/contractsVerified');
  const html = await response.text();

  // Extract the verified contracts from the HTML
  const verifiedContracts = html.match(/href="\/address\/[0-9a-fA-F]+"/g)
    .map((link) => link.slice(8, -1));

  // Send an embedded message to the Discord channel with the verified contracts
  const embed = new Discord.MessageEmbed()
    .setTitle('Verified Contracts')
    .setDescription(verifiedContracts.join('\n'))
    .setColor('#00FF00');
  channel.send(embed);
}, 60000);

client.login(config.BOT_TOKEN);

Here is the error I'm getting--

TypeError: Cannot read properties of null (reading 'map')
    at Timeout._onTimeout (/root/project1/index.js:27:5)
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)

Any help would be greatly appreciated. Thank you!
