I am facing issue if app not installed on phone getting this message on alert "Safari cannot open the page because the address is invalid." I want to bypass this alert and show my custom alert message. I am using this for open then app.

  (function () {
                var app = {
                    launchApp: function () {
                        window.location = "com.test://scan?code=1";
                        this.timer = setTimeout(this.openWebApp, 500);
                    }
                };
                app.launchApp();
            })();
