After upgrade from magento 2.3.2 to 2.3.3 I get this error while Compilation:

Fatal error: Declaration of Magento\QuoteGraphQl\Model\Cart\SetShippingAddressOnCart::execute(Magento\Framework\GraphQl\Query\Resolver\ContextInterface $context, Magento\Quote\Api\Data\CartInterface $cart, array $shippingAddresses): void must be compatible with Magento\QuoteGraphQl\Model\Cart\SetShippingAddressesOnCartInterface::execute(Magento\GraphQl\Model\Query\ContextInterface $context, Magento\Quote\Api\Data\CartInterface $cart, array $shippingAddressesInput): void in /home/ttu52076/public_html/vendor/magento/module-quote-graph-ql/Model/Cart/SetShippingAddressOnCart.php on line 20

Any help?

Thanks

Backup and delete the file /vendor/magento/module-quote-graph-ql/Model/Cart/SetShippingAddressOnCart.php

The error is pretty specific: the declaration of your class 'method must be compatible with the declaration of the class' method in the interface.

Do you have an override of Magento\QuoteGraphQl\Model\Cart\SetShippingAddressOnCart?

Because somewhere in 2.3, the interface for the execute method had an argument that changed from Magento\Framework\GraphQl\Query\Resolver\ContextInterface to Magento\GraphQl\Model\Query\ContextInterface (see this change). If you ever overrode that method, then you will need to update the $context argument to match the class specified in the interface.
