Svg sprite icons not show after parcel


I have svg sprite icons properly showing on local server ( But after I tried parcel index.html, svg sprite icons disappeared (localhost:1234). svg sprite icons don’t show on netlify after I deployed it neither. Does anyone know why? Any input will be very appreciated.

my system:
node: 14.15.1
npm: 6.14.8
parcel: 2.0.0-beta.3.1
macos catalina 10.15.7

Thank you for help.
