I keep getting the same error. I have not touched Webpacker for the past 5 builds, and suddenly getting errors for a small change in some simple code. Really starting to baffle me.
I seem to be getting a space in the word 'loader', on the 'ERROR in Error line (4). I feel that is the cause.
Here is the output error:
WARNING in webpack performance recommendations:
You can limit the size of your bundles by using import() or require.ensure to lazy load some parts of your application.

Notice the use of %PUBLIC_URL% in the tags above.
It will be replaced with the URL of the `public` folder during the build.
Only files inside the `public` folder can be referenced from the HTML.
Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
work correctly both with client-side routing and a non-root public URL.
Learn how to configure a non-root public URL by running `npm run build`.

Just got the same error, even though everything was locked down with package-lock.json files, and was building successfully 2 days ago.
Updating html-webpack-plugin and webpack helped:
npm install webpack@latest
npm install html-webpack-plugin@latest
