Deeplink url for OAuth 2.0 redirect url

I using the deep link for generating a custom URL. I have installed it as
ionic cordova plugin add ionic-plugin-deeplinks --variable URL_SCHEME=sf --variable DEEPLINK_SCHEME=https --variable DEEPLINK_HOST=sfapp.com --variable ANDROID_PATH_PREFIX=/. I’m using OAuth 2.0 for 3 party app integration. Where I use

sf://sfapp.com/callback
as my redirect URL.
But it pops an error message as
OAuth 2.0 redirect URLs must be HTTP or HTTPS.
so, how can I solve this issue?
