If you want to show products category wise, then use this inside "Home Page Content" - @include('shop::home.category', ['category' => 'category_name'])

@Vaishali-Agarwal - Problem solved.

You can see my previous version is working fine here - https://phpstack-378818-1259319.cloudwaysapps.com/

@Vaishali-Agarwal I tried but didn't find any issue. That's why I posted here with my source code.

@Vaishali-Agarwal I think there is no problem in Bagisto 1.2 . This error is showing only when I'm adding my payment package.

@Vaishali-Agarwal

If I remove my payment package the checkout works. But when I add again the error shows.

@Vaishali-Agarwal No

Those changes are already there in my packages/Webkul/Checkout/src/Cart.php

private function linkAddresses(
        \Webkul\Checkout\Models\Cart $cart,

            $this->cartAddressRepository->update($billingAddressData, $billingAddressModel->id);

            if ($cart->haveStockableItems()) {
                $shippingAddressModel = $cart->shipping_address;
