Description

Stripe Checkout recently added Cash App Pay as an option for recurring payments, however using this with Cashier causes a 500 error for the webhooks customer.updated and customer.subscription.updated with the ErrorException: Attempt to read property "last4" on array. This is coming from the optional($paymentMethod)->$type->last4 code in ManagesPaymentMethods.php.

This happens apparently due to Cash App not providing that last4 attribute, but it is strange because the Link payment method also doesn't have the attribute but works just fine with the same webhooks.

The intended behavior is it should set the pm_type on the User model to cashapp with no error after checkout. Simply fixing this issue with the webhook should allow full support of Cashier with Cash App Pay via Stripe Checkout.

Steps To Reproduce

Use a Stripe Checkout with Cash App Pay for a recurring subscription and the webhooks that follow will trigger the above error.

Hmm that's odd. I guess this payment method doesn't have that object key. I can't find an example of a full cashapp object. Do you have one?

From charge.succeeded it looks like this:

"payment_method_details": {
  "cashapp": {
  },
  "type": "cashapp"
}

Let me know if you need anything else for it.
