[RealRajnish]

if (action.type === "CART_ITEM_PRICE_TOTAL") {
        let { total_item, total_price } = state.cart.reduce(
            (accum, curElem) => {
                let { price, amount } = curElem;

                accum.total_item += amount;
                accum.total_price += price * amount;

                return accum;
            },
            {
                total_item: 0,
                total_price: 0,
            }
        );
        return {
            ...state,
            total_item,
            total_price,
        };

Yes , it has been fixed.

I'm having same problem?

it is causing because , i guess somewhere you have used localstorage . it was causing error due to that code just fix that.

Change your code in cart context

const getLocalCartData = () => {
let localCartData = localStorage.getItem("thapaCart");
const parsedData = JSON.parse(localCartData);
if (!Array.isArray(parsedData)) return [];
return parsedData;
};
