On initial page load, the site runs fine and loads the proper data, but when I try to change some of the content, and check to see if hot-reloading is working, it throws these errors.
Error: The selector "app" did not match any elements

Since it's loading on the initial load, I'll just post my package.json and webpack.config.js. If more files are needed, I'll post them ASAP.
Any help or guidance is greatly appreciated.
Here's my package.json. I'm running npm run watch in one console and npm run start:hmr in another console.
