Upgrade to Magento 2.4.7 error in module-payment-services-base

Question

After upgrading from Magento 2.4.6 to 2.4.7 I receive the following error, everytime I try to access to payment method configuration (Stores -> Configuration -> Sales -> Payment Methods):

Exception: Warning: Undefined array key "children" in /var/www/html/vendor/magento/module-payment-services-base/Plugin/MovePaymentMethods.php on line 66 in /var/www/html/vendor/magento/framework/App/ErrorHandler.php:62

Question: Any ideas to solve that issue?

• Herve Tribouilloy: I’ll take a look tomorrow
• Dhiren Vasoya: If you have any third party extension of payment method, then try to disable it and then check.
• Martin K.: it was a vanilla installation. I could fix that with disabling all paypal modules. But I would like to find a more easy way.
• Herve Tribouilloy: The plugin MovePaymentMethods is not enabled by anything in a vanilla install as far as I see it. In this case, 1. you should be able to disable this plugin. 2. it seems something else enables the plugin and that may be a third-party module indeed
• Martin K.: strange ok I have some third-party modules but all of them are not related to MovePaymentMethods. I will investigate.

• Juliano Vargas: Any ideas why this is happening? I have 5 websites with each having 1 store view but only one website/store is having this issue.

Answer 2

the problem seems to be the "new Adobe payment" plugin. The solution above "MovePaymentMethods.php" works but strangely on one server the problem did not occur after upgrade to 2.4.7

Answer 3

As a workaround, you can disable the plugin from a custom module. etc/adminhtml/di.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <type name="Magento\Paypal\Model\Config\Structure\PaymentSectionModifier">
 <plugin name="move_express_checkout_us_to_other_paypal_payment_solutions" disabled="true"/>
 </type>
</config>
