    hi

    The framework can only handle pages with an object of the return type.

    It is working fine on popup pages. Can you suggest a way to show the userfriendlyexception on index page from appservice without a return type?

    It is working fine on popup pages.

    This is because you are calling API, and the page cannot display such a style.

    You can check the Page-Alerts

    Alert is not showing on appservice page.

    _alertManager.Alerts.Warning( text: L["ExpirationDateValidationMessage"], title: "Service Interruption" );
