getInvitation() not working

[saiy2k]

I click on the Invite link in my mail, the app gets opened, but the FirebaseInvites.getInvitation() is not working

    this.logger.info("Signup Component :: On Page Loaded :: Start 1");

    FirebaseInvites.getInvitation(
        function (result) {
            console.log("invitation ID: " + result.invitationId);
            console.log("deeplink: " + result.deepLink);
        },
        function (msg) {
            alert("Firebase Invite Error: " + msg);
        }
    );

    this.logger.info("Signup Component :: On Page Loaded :: Start 2");

I am getting both the On Page Loaded logs, but not the Firebase success/error logs.
