NPE in MobileRegistration.java

[The-PaulQuappe]

Hey!

I just tried to use this library with the the mobileBuilder, but i encountered a NPE in MobileRegistration toFormParameters, because on the exists() callBack toFormParams are created with useToken false resulting in a null token on which .length() gets called.. Am i somehow doing the Flow wrong in the first place or is this just a bug?

i tried to follow the example from the readme:
		Whatsapp api = Whatsapp.mobileBuilder()
				.newConnection()
				.name("test")
				.device(CompanionDevice.android(new Version(2,25,28,79,0),false,null))
				.unregistered()
				.verificationCodeMethod(VerificationCodeMethod.SMS)
				.verificationCodeSupplier(() -> {
					System.out.println("Enter OTP: ");
					var scanner = new Scanner(System.in);
					return scanner.nextLine();
				})
				.register(PHONE_NUMER)
				.join()
				.whatsapp()
				.addLoggedInListener(whatsapp -> System.out.printf("Connected: %s%n", whatsapp.store().privacySettings())) 
				.addDisconnectedListener(reason -> System.out.printf("Disconnected: %s%n", reason)) 
				.addNewChatMessageListener(message -> System.out.printf("New message: %s%n", message)) 
				.connect()
				.join();
