When user adds an item(or items) to the cart, it behaves normally. but if user tried to goto either checkot page or basket page after a while, it shows an error page as follows,
Exception #0 (Magento\Framework\Exception\NoSuchEntityException): No such entity with cartId =
Exception #0 (Magento\Framework\Exception\NoSuchEntityException): No such entity with cartId =
#0 E:\xampp\htdocs\magento_projects\jestic\vendor\magento\module-quote\Model\QuoteRepository.php(197): Magento\Framework\Exception\NoSuchEntityException::singleField('cartId', NULL)

#10C:xampp/htdocs/myProject/vendor/magento/module-checkout/Block/Cart/Shipping.php(54): Magento\Checkout\Model\CompositeConfigProvider->getConfig()
and so on..
This happens when user tries to click on minicart icon before site gets fully loaded. (icon is clickable before site gets fully loaded and it linked to http://localhost/myProject/checkout/cart/)
I think usually there should be some standard web page with error message rather than showing errors like this.
What is wrong here? How can I fix this? please help…
