Iterating the creation of objects with asynchonous javascript map method data [duplicate]

In an async IIFE at the bottom of this javascript, you'll see that I'm trying to: 1) read a JSON file, 2) get multiple RSS feed URLs from that data, 3) pull and parse the data from those feeds, and create an object with that data, so I can 4) write that pulled RSS data object to a JSON file. Everything for #1 and #2 is fine. I'm able to pull data from multiple RSS feeds in #3 (and log it to console), and I'm comfortable handling #4 when I get to that point later.

My problem is that, at the end of step #3, within the const parseFeed function, I am trying to create and push an object for that iteration of rssJSONValsArr.map() in the IIFE and it's not working. The rssFeedDataArr result is empty. Even though I am able to console.log those values, I can't create and push the new object I need in order to reach step #4. My creating of a similar object in #2 works fine, so I think it's the map I have to use within const parseFeed to pull the RSS data (using the rss-parser npm package) which is making object creation not work in step #3. How do I get rssFeedOject to work with the map data?

import fs from 'fs';
import path from 'path';
import { fileURLToPath } from 'url';
import Parser from 'rss-parser';
const parser = new Parser();

const __filename = fileURLToPath(import.meta.url);
const __dirname = path.dirname(__filename);

const feedsJSON = path.join(__dirname, 'rss-feeds-test.json');

const rssJSONValsArr = [];
const rssFeedDataArr = [];

const pullValues = (feedObject, i) => {
  const url = feedObject.feed.url;
  const jsonValsObject = {
    url: url,
  };
  rssJSONValsArr.push(jsonValsObject);
};

const parseFeed = async (url) => {
  try {
    const feed = await parser.parseURL(url);

    feed.items.forEach((item) => {
      console.log(`title: ${item.title}`); // correct
    });

    const rssFeedOject = {
      title: item.title,
    };
    rssFeedDataArr.push(rssFeedOject);
  } catch (err) {
    console.log(`parseFeed() ERROR 💥: ${err}`);
  }
};

(async () => {
  try {
    console.log('1: read feeds JSON file');
    const feedsFileArr = await fs.promises.readFile(feedsJSON, {
      encoding: 'utf-8',
    });
    const jsonObj = JSON.parse(feedsFileArr);

    console.log('2: get feed URLs');
    jsonObj.slice(0, 30).map(async (feedObject, i) => {
      await pullValues(feedObject, i);
    });
    console.log('rssJSONValsArr: ', rssJSONValsArr); // correct

    console.log('3: pull data from rss feeds');
    rssJSONValsArr.map(async (feedItem, i) => {
      await parseFeed(feedItem.url, i);
    });
    console.log('rssFeedDataArr: ', rssFeedDataArr); // empty !!!

    // console.log('4: write rss data to JSON file');
    // await fs.promises.writeFile(
    //   `${__dirname}/rss-bulk.json`,
    //   JSON.stringify(rssFeedDataArr)
    // );

    console.log('5: Done!');
  } catch (err) {
    console.log(`IIFE CATCH ERROR 💥: ${err}`);
  }
})();

Example JSON file with two RSS feed URLs:

[
  {
    "feed": {
      "details": {
        "name": "nodejs"
      },
      "url": "https://news.google.com/rss/search?q=nodejs"
    }
  },
  {
    "feed": {
      "details": {
        "name": "rss-parser"
      },
      "url": "https://news.google.com/rss/search?q=rss-parser"
    }
  }
]

Any and all help appreciated. Thanks
