		return new CustomerInfoResponse(

It seems like DateTimeImmutable::createFromFormat('YmdHis', $data['dttm']) can also be of type false; however, parameter $responseDateTime of SlevomatCsobGateway\Call\CustomerInfoResponse::__construct() does only seem to accept DateTimeImmutable, maybe add an additional type check?

			ResultCode::get($data['resultCode']),
			$data['resultMessage'],
			$data['customerId'] ?? null
		);
