The error is: `Cannot resolve file 'favicon.ico'`
The file is located in the public directory which is marked as a resource root.

https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000006044-How-to-set-html-root-directory - The author mentioned that having the resource root in .gitignore caused the "cannot resolve file" error. I tried removing `/dist/` from .gitignore with no change.
