Error when registering device for push notifications from channels.

[vikram25897]

I have added FCM server key on the dashboard, and I am trying to register my device for push notifications from channels like this:
await client.addPushChannels(fcmToken, PushGateway.fcm, channelSet);

However I am receiving this error:

E/flutter (13240): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: PubNubException: null error: Invalid type argument
E/flutter (13240): #0 new PubNubException (package:pubnub/src/core/exceptions.dart:6:29)
E/flutter (13240): #1 getExceptionFromDefaultResult (package:pubnub/src/dx/_utils/exceptions.dart:31:10)

E/flutter (13240):
E/flutter (13240): #4 PushNotificationDx.addPushChannels (package:pubnub/src/dx/push/push.dart:74:12)

I also tried calling it other way like:

await client.device(fcmToken).registerToChannels(channelSet, PushGateway.fcm);

But the error stays the same. Any ideas about what could it be?
