Build command appears not creating manifest.json file

[rianfloo]

Hi :)

I used your wonderful boilerplate for a project. Everything works perfectly on localhost. On production mode, I've got an error in the browser console:

manifest.json:1 Manifest: Line: 1, column: 5, Unexpected data after root element.
The attempt to bind "/%PUBLIC_URL%/manifest.json" in the workspace failed as this URI is malformed.
GET https://fake-appp-url.web.app/%PUBLIC_URL%/manifest.json

I've checked locally and the command npm run build doesn't generate manifest.json.

Any ideas?

Thanks a lot! :)
