XF 2.2 Stripe Payment Error

[Razed-]

Edit: I solved the problem. The issue was the 'User Upgrade' price was set too low ($0.01) for testing purposes. Increasing that to $1 fixed it.

Hello,

Getting an error when trying to pay for a user upgrade via Stripe. Any idea what could be the cause? I'm running v2.2.10 Patch 1.
Payment Provider log is empty.

When trying to pay from a regular user account:

[E_WARNING] Attempt to read property "status" on null - src/XF/Payment/Stripe.php:393

#0 src/XF/Payment/Stripe.php(393): XF::handlePhpError(2, '[E_WARNING] Att...', '/var/www/html/g...', 393)

Line 393 on Stripe.php is:

$paymentStatus = $latestInvoice->payment_intent->status;

My Stripe webhook is reading the following endpoints:

account.updated
charge.dispute.funds_withdrawn
charge.dispute.funds_reinstated
charge.refunded
charge.succeeded
invoice.payment_succeeded
review.closed

Thanks for your help
