Checkout Page Not Loading After Upgrading from Magento 2.4.5-p5 to 2.4.6-p7

Question

I recently upgraded my local Magento Enterprise edition from version 2.4.5-p5 to 2.4.6-p7. After resolving some Zend framework-related issues, most functionality is working correctly. However, the checkout page is not loading, and in the console, I’m seeing an error: window.checkoutConfig.quoteData not found.

I’ve checked the block class, but it's returning empty data. Strangely, when I downgrade back to Magento 2.4.6-p5, everything works as expected.

Any assistance or insights would be greatly appreciated.

This happens because of changes to Content Security Policy (CSP) to comply with PCI 4.0 requirements. After update the checkout page CSP mode changed from report_only to strict. As a temporary solution you can add the following to your env.php

'system' => [
        'default' => [
            'csp' => [
                'mode' => [
                    'storefront_checkout_index_index' => [
                        'report_only' => '1'
                    ],
                    'admin_sales_order_create_index' => [
                        'report_only' => '1'
                    ]
                ],
                'policies' => [
                    'storefront_checkout_index_index' => [
                        'scripts' => [
                            'inline' => '1'
                        ]
                    ],
                    'admin_sales_order_create_index' => [
                        'scripts' => [
                            'inline' => '1'
                        ]
                    ]
                ]
            ]
        ]
    ]
