I’m not expert but no one else responded … the little I know is it is to do with Android and its web browser/webport not allowing URLS that start with things (schemes) like
whatsapp://…
Compare that URL to https://…
You probably need to google something like “How to open whatsapp from a link on an android phone?”
The error ERR_UNKNOWN_URL_SCHEME happens when your app or browser encounters a URL scheme that it doesn’t recognize or doesn’t know how to handle. This is common with schemes other than the standard “http://” or “https://”, and specifically mentions “whatsapp://” as one that might cause this issue if not handled correctly. It is generally a browser-related problem that appears when the browser is able to process a URL that it simply doesn’t know how to handle. URL scheme is the first element of a URL that defines the protocol that is necessary.
The possible solution can be as:-
Implement a handler (Intent) in the app’s code to handle the “whatsapp://” scheme and launch WhatsApp.
Verify the WhatsApp URL scheme’s correct format.
Consider adding the QUERY_ALL_PACKAGES permission for Android 12+ devices.
As, there are many causes for it, I found the helpful resource article in detail at:- https://cheapsslweb.com/resources/how-to-resolve-err_unknown_url_scheme-error. I hope it helps!
