PushServiceInvalidTokenError

Thrown when the push token provided to PushService.registerPushToken or PushService.unregisterPushToken is empty or consists entirely of whitespace characters.

To resolve this, ensure that a valid, non-empty token string obtained from the push service provider is passed in the options object before calling these methods.

See: PushService.registerPushToken, PushService.unregisterPushToken
