Configuring Omnipay-stripe to work with PCI SCA using Laravel

Question

I'm following the example on Stripe Payment Intents to enable PCI SCA card processing, but receive the following error:

dev.ERROR: Call to undefined method Omnipay\Stripe\Message\Response::getPaymentIntentReference()

The code section is copied from the example:

$response = $gateway->authorize($purchaseVals)->send();

$paymentIntentReference = $response->getPaymentIntentReference();

$response = $gateway->confirm([
                                'paymentIntentReference' => $paymentIntentReference,
                                'returnUrl' => $completePaymentUrl,
                              ])->send();

Does anyone have a clue as to what I'm doing wrong?

Edit: Versions!

• Laravel Framework 5.8.38
• phpleague/omnipay-stripe 3.1.0
