Failed to load resource: the server responded with a status of 503 (Service Unavailable) http://localhost:8000/IconResLow.png


When my PWA/Web App starts in browser I have info that the resource http://localhost:8000/IconResLow.png is unavailable. Yes, because URL for my project is http://localhost:8000/test/ and in test I have IconResLow.png.
Should I change some settings to avoid this error?

Edit manifest.json and change the references to these icon files to specify the subfolder.
