I am trying to develop a mobile app for my web site created in magento 2.
While adding a product into the cart (addToCart), i am getting following error in the logs:
Fatal error: Declaration of Magento\Checkout\Helper\Data\Proxy::sendPaymentFailedEmail(Magento\Quote\Model\Quote $checkout, string $message, string $checkoutType = 'onepage') must be compatible with Magento\Checkout\Helper\Data::sendPaymentFailedEmail(Magento\Quote\Model\Quote $checkout, string $message, string $checkoutType = 'onepage'): Magento\Checkout\Helper\Data in /public_html/generated/code/Magento/Checkout/Helper/Data/Proxy.php on line 7
Can someone help me to understand what does it means and how to resolve this error.
