		$response = $apiClient->put(

		return new PaymentResponse(
			$data['payId'],
			DateTimeImmutable::createFromFormat('YmdHis', $data['dttm']),

It seems like DateTimeImmutable::createFromFormat('YmdHis', $data['dttm']) 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']),
			$data['resultMessage'],
			isset($data['paymentStatus']) ? PaymentStatus::get($data['paymentStatus']) : null,
			$data['authCode'] ?? null
		);
	}
