It seems like $responseDateTime can also be of type false; however, parameter $responseDateTime of SlevomatCsobGateway\Call\PaymentResponse::__construct() does only seem to accept DateTimeImmutable, maybe add an additional type check?

			ResultCode::get($data['resultCode']),
			$data['resultMessage'],
