I'm currently trying to make a node.js script to read a couple of RSS feeds from a JSON file (config.json), check everyone and send new items to it's specific webhook for Discord.

The config file is the following:

[
  {
    "name": "r/aww",
    "avatar": "https://example.com/avatar.jpg",
    "rss_url": "https://www.reddit.com/r/aww/top/.rss",
    "webhook_url": "https://discord.com/api/webhooks/..."
  },
  {
    "name": "r/ImaginaryLandscapes",
    "avatar": "https://example.com/avatar.jpg",
    "rss_url": "https://www.reddit.com/r/ImaginaryLandscapes/top/.rss",
    "webhook_url": "https://discord.com/api/webhooks/..."
  }
]

And the code that i attempted to do, following sync examples from rss-parser npm package, is the following:

let Parser = require('rss-parser');

let parser = new Parser();

const config = require("./config.json");

config.forEach(element => {
    
    parser.parseURL(element.rss_url, function(err, feed) {
      console.log(feed);

      feed.items.forEach(function(entry) {
        console.log(entry.title + ':' + entry.link);
      });
    });

});

But trying to run it throws the following error:

undefined
/mnt/d/misc/feedchecker/script.js:28
          feed.items.forEach(function(entry) {
               ^

TypeError: Cannot read property 'items' of undefined

What I'm doing wrong on this code? Please note that i still didn't wrote the webhook sending part, I'm focused still on fetching the feeds first.
