Getting unsafe url error

I’m trying to open a whats’app link and I’m getting thus error :

WARNING: sanitizing unsafe URL value SafeValue must use

here is my code :

<a href="{{surl}}">
<img src="assets/imgs/whatsapp.png" height=35px/></a>

and in the ts file here is what surl holds :

this.url = 'whatsapp://send?text=Hello World!&phone=+966'
this.surl = this.dom.bypassSecurityTrustUrl(this.url);

the problem as you can tell is that I’m passing a variable to the url , but cordova won’t trust it !
any ideas how can I solve this problem ?

any ideas for solutions guys ?

Answered here. You’re undoing the sanitization by using interpolation.
