[ECP-9346]$txVariant is null when trying to vault a Google Pay Mastercard

[jsterling]

Describe the bug
When trying to save a GooglePay Mastercard to vault we see the following failure:

Adyen\Payment\Model\Method\TxVariant::__construct(): Argument #1 ($txVariant) must be of type string, null given, called in ****/vendor/adyen/module-payment/Helper/Vault.php on line 207

It looks like $payment->getCcType() is null; however 'mc_googlepay' is stored in db tables for these payments.

The payment still goes through and order is created, but it causes a 500 error in checkout call to /adyen/carts/mine/payments-details and it appears that the payment has failed; meaning customers are processing the same payment again - it'll fail a second time on mc_googlepay but go through on later attempts with a different Google Pay funding source, or typed card details; but they end up with multiple orders and confirmation emails are async so not getting to them immediately.

Expected behavior
Google Pay Mastercard payments vault correctly and no error is generated

Hello @jsterling,

Let me jump into the discussion. This reminds me a configuration issue. Did you enable mc_googlepay and visa_googlepay tx variants on your Adyen Customer Area Payment Methods page? Could you please also confirm that you've enabled all the required additional data fields described on Step 2: Set up recurring contracts in Adyen?

Best regards,
Can

@candemiralp Thank you.

All GooglePay variants seem to be enabled (except one - this is inactive on all our merchant accounts, I believe the team are checking with merchant support as to why it would be inactive); and I can confirm that all additional data is set up correctly.
