Not able to log in using phone number in gigya

[swastiiijain]

I am trying to login to gigya using my phone number. I already registered in gigya using my phone number but when I tried to log in by calling the Standard-3.0-Registration, it is saying Invalid Login. However email log in is working fine.
Below is the code and screenset I am using in flutter:

void standardScreenSet30() {
widget.sdk.showScreenSet('Standard-3.0-RegistrationLogin', parameters: {
'deviceType': 'Mobile',
'lang': 'en',
}).listen((event) {
print('EVENT : ' + event.toString());
});
}

@override

Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: ElevatedButton(
onPressed: standardScreenSet30,
child: const Text('show-screenset')),
),
);
}
