Undefined index and undefined variable errors in paypalwpp

[Dave224]

Ever since January 3, 2022, every PayPal Express Checkout order has triggered the following errors:

• Undefined index: PAYMENTREQUEST_0_ADDRESSSTATUS in line 1847 of paypalwpp.php
• Undefined variable: country_code3 in paypalwpp.php lines 1983, 1997, and 2010
• Undefined index: countries_id in paypalwpp lines 2022 and 2075

A PayPal EC on January 2 did not trigger these notices. All orders were for virtual products. I transitioned to zc157c on the production server on January 1. Has anyone else experienced these errors, especially this year?

php 7.3.27

Was this transition to 1.5.7, 1.5.7c, or to the latest of the v157 branch in Github?

The version is 1.5.7c.

I forgot to add one other undefined variable notice to the list in my first post in this thread: address_book_id on line 2075 in paypalwpp.php

Initial review of code related to the above batista indicates that these issues may be previously unreported and seem to be yet unresolved. When say virtual product, could you 1, identify the product settings in the virtual section, the address required section and settings in that vicinity and 2, explain what makes this a virtual product and not simply a download?
