Awaiting feedback PayPal Payment Profile

[stromb0li]

Affected version

2.3.2

I keep seeing these errors repeat in server logs using the new PayPal payment profile.

ErrorException: [E_WARNING] Undefined array key "alternate_accounts" src/XF/Payment/PayPal.php:386

#0 src/XF/Payment/PayPal.php(386): XF::handlePhpError(2, '[E_WARNING] Und...', '/var/www/...', 386)
#1 payment_callback.php(57): XF\Payment\PayPal->validatePurchasableData(Object(XF\Payment\CallbackState))
#2 {main}

Using PHP 8.2.15

Here's a fix for those that are heavily dependent on the response from PayPal for their add-ons.

Replace line 386 with these two:

$alternate_acccounts = empty($options['alternate_accounts']) ? [] : $options['alternate_accounts'];
$accounts = Arr::stringToArray($alternate_acccounts, '#\r?\n#');

Looks like there is another after the fix as well:

ErrorException: [E_WARNING] Undefined array key "primary_account" src/XF/Payment/PayPal.php:388

#2 {main}

Are both primary_account and alternate_accounts expected to be specified? What are these values supposed to be (usernames, user_id, etc)?

This error is in reference to the old PayPal payment profile. Presumably you have deleted the old payment profile? Is it possible you have old recurring purchasables from the old profile which may be sending IPNs?

They are email addresses, and part of the configuration for the old PayPal payment profile.

Yes, this is correct that the old payment profile was deleted.

No, we don't have any recurring payments.

They are email addresses, and part of the configuration for the old PayPal payment profile.

Do I need to explicitly turn off IPN for payment even after using the Rest API? I had figured it wouldn't be used for any new transactions post-migration to the new PayPal provider.

Maybe, you can check the IPN history page on your account to see if it's still sending requests and what transactions they might be stemming from: https://www.paypal.com/merchantnotification/ipn/history

I got this same error here:

ErrorException: [E_WARNING] Undefined array key "alternate_accounts" src/XF/Payment/PayPal.php:386

What is the exact cause of the error on this?
