After upgrade magento 2.3.5 to 2.4.3, Can't update product quantity to minicart

Question

I can't update product quantity in mini cart after upgrading the Magento 2.3.5 to 2.4.3-p2 version. I got this below error

Notice: Trying to access array offset on value of type int in /var/www/html/magento_storefront/vendor/magento/zendframework1/library/Zend/Locale/Format.php on line 523

Anyone can you please guide me?

Answer 1

Please run the below commands and check:

1. php bin/magento setup:upgrade
2. php bin/magento setup:static-content:deploy -f
3. php bin/magento cache:flush

If Still issue persists

1. Check if there is any error on Browser console? During Update in MiniCart
2. Check the system.log & exception.log
3. Try using Luma Theme once, if you are using custom theme, to be sure, you have no issues on your custom theme.
