authorize.net in 2.10

This may be a bug but I can't find any reference anywhere to it the forum.

The error log reads
[20-Feb-2026 04:03:27 America/Los_Angeles] Request URI: /index.php?main_page=checkout_confirmation, IP address: 84.20.18.200, Language id 1

--> PHP Warning: Undefined array key "authorizenet_aim_cc_cvv" in /includes/modules/payment/authorizenet_aim.php on line 319.

I did delete the module and reinstall it when this arose as I had not done so at the upgrade but the error message persists. It repeats many times but no order happens even in the same day as all

The tpl_checkout_confirmation_default.php file is standard - not a template issue and all modules/pages/ files are also standard with no additions. As is the classes/payment.php file.

I did check to be sure and yes the admin setting to request the cvv is turned to true.

I'm attaching a screenshot of the error logs page so that you can see how many times this happens out of the first 20 files.

When you see the authorize.net/aim form, is the CVV field included? It should be if you've enabled that in the a.net configuration.

it does show up on the checkout payment screen.

Anyone? is this a bug?
