CodeIgniter Omnipay Przelewy24: Message: The email parameter is required - codeigniter-3

Question

I try enable payment gateway Przelewy24 with Omnipay library for Codeigniter 3.
For this I install via composer both libraries.
Library:
https://github.com/mysiar-org/omnipay-przelewy24v1
and
https://github.com/thephpleague/omnipay
Then I create controller
Cart_contoller.php I add function
use Omnipay\Omnipay;
/**
* Payment with Przelewy24
*/
public function przelewy24_payment_post()
{
$przelewy24 = get_payment_gateway('przelewy24');
if (empty($przelewy24)) {
$this->session->set_flashdata('error', "Payment method not found!");
echo json_encode([
'result' => 0
]);
exit();
}
/** #var \Omnipay\Przelewy24\Gateway $gateway */
$gateway = Omnipay::create('Przelewy24');
$gateway->initialize([
'merchantId' => 'xxxx',
'posId' => 'xxxx',
'crc' => 'xxxxxxxxxxxx',
'testMode' => true,
]);
$params = array(
'sessionId' => 2327398739,
'amount' => 12.34,
'currency' => 'PLN',
'description' => 'Payment test',
'returnUrl' => 'www.xxxxxx',
'notifyUrl' => 'www.xxxxxxxxxxx',
'card' => array(
'email' => 'info#example.com',
'name' => 'My name',
'country' => 'PL',
),
);
$response = $gateway->purchase($params)->send();
if ($response->isSuccessful()) {
$response->redirect();
} else {
echo 'Failed';
}
}
in view page I add:
<?php echo form_open('cart_controller/przelewy24_payment_post'); ?>
<div class="payment-icons-container">
<label class="payment-icons">
<?php $logos = #explode(',', $payment_gateway->logos);
if (!empty($logos) && item_count($logos) > 0):
foreach ($logos as $logo): ?>
<img src="<?php echo base_url(); ?>assets/img/payment/<?= html_escape(trim($logo)); ?>.svg" alt="<?= html_escape(trim($logo)); ?>">
<?php endforeach;
endif; ?>
</label>
</div>
<button id="submit" class="btn btn-primary" id="card-button">
<span class="spinner-border spinner-border-sm" role="status" aria-hidden="true"></span>
<?= trans("pay"); ?> <?= price_formatted($total_amount, $currency); ?>
</button>
<?php echo form_close(); ?><!-- form end -->
On button submit I get:
Type: Omnipay\Common\Exception\InvalidRequestException
Message: The email parameter is required
What I do wrong? Can anyone help me with this code how to correct integrate this gateway?
