Hi guys!! I´m studying and got a Full stack course but the course lacked a lot of support and and info to learn as it´s a course after work and lasted 5 months. The final project is a ecommerce and the backend was built in class so I do understand the idea but I´m lacking to understand the issues when there´s something wrong aside from getting products on seed

long story short I´m struggling to finish one of the last requirements which is when I click on my submit button gives me a error that I dont understand which is:
Erro ao enviar o pedido. Detalhes:

Cannot POST /orders

it seems on backend everything is fine and my FE where I have my products list is:

Blockquote// ProductList.tsx
import React from “react”;
import SortBy from “./SortBy”;
import formatCurrency from “…/helpers/FormatCurrency”;
import “./ProductList.css”;

interface Product {
_id: string;
imageUrl: string;
hoverImageUrl: string;
alt: string;
name: string;
price: number;
}

interface ProductListProps {
searchQuery: string;
addToCart: (product: Product) => void;
selectedCurrency: string;
convertCurrency: (amount: number, from: string, to: string) => number;
}

const ProductList: React.FC = ({
searchQuery,
addToCart,
selectedCurrency,
convertCurrency,
}) => {
const [localProducts, setLocalProducts] = React.useState<Product>();
const [loading, setLoading] = React.useState(true);
const [error, setError] = React.useState<string | null>(null);

React.useEffect(() => {
const fetchProducts = async () => {
try {
const response = await fetch(“http://localhost:3000/products”);
if (!response.ok) {
throw new Error(“Network response was not ok”);
}
const data: Product = await response.json();
setLocalProducts(data);
setLoading(false);
} catch (error) {
setError(“Failed to fetch products.”);
setLoading(false);
console.error(“Failed to fetch products:”, error);
}
};

fetchProducts(); 

}, );

const sortAscending = () => {
const sortedProducts = […localProducts].sort((a, b) => a.price - b.price);
setLocalProducts(sortedProducts);
};

const sortDescending = () => {
const sortedProducts = […localProducts].sort((a, b) => b.price - a.price);
setLocalProducts(sortedProducts);
};

const sortNameAZ = () => {
const sortedProducts = […localProducts].sort((a, b) =>
a.name.localeCompare(b.name)
);
setLocalProducts(sortedProducts);
};

const sortNameZA = () => {
const sortedProducts = […localProducts].sort((a, b) =>
b.name.localeCompare(a.name)
);
setLocalProducts(sortedProducts);
};

const showFeatured = () => {
// Lógica para mostrar produtos em destaque
console.log(“Show Featured”);
};

const filteredProducts = localProducts.filter((product) =>
product.name.toLowerCase().includes(searchQuery.toLowerCase())
);

const productsToShow = searchQuery ? filteredProducts : localProducts;

const handleAddToCart = (product: Product) => {
// Converte o preço para a moeda selecionada
const convertedPrice = convertCurrency(
product.price,
“EUR”,
selectedCurrency
);
// Adiciona ao carrinho com o preço convertido
addToCart({ …product, price: convertedPrice });
};

return (

export default ProductList;

> Blockquote

if someone can help me understand or where is the blocker I would be super appreciated , thank you!!
