Question

After upgrading from 2.3.5 to 2.4.3 in local setup, while adding to cart shows an error as shown in the below screenshot

There are some third-party modules that I tried disabling but then the site couldn't able to load. There are no logs generating in the var/logs folder

Please let me know if you have any solutions.

Answer 1

Somehow found a solution.

There was a custom module which was causing this issue specifically below code,

 // \Magento\Framework\App\Http\Context $this->httpContext
 $isLoggedIn = $this->httpContext->getValue(\Magento\Customer\Model\Context::CONTEXT_AUTH);

So used this class Magento\Customer\Model\SessionFactory instead of \Magento\Framework\App\Http\Context

Hope this helps.
