英文:
I have an issue with my ecommerce web application
问题
以下是翻译好的部分：
"Can anybody help me with this error? I followed an ecommerce example application, but at the end, I encountered an error when I clicked on "Shop Now." This is the message I received:
Server Error
TypeError: Cannot destructure property 'image' of 'product' as it is null.
This error happened while generating the page. Any console logs will be displayed in the terminal window.

pages\product[slug].js (19:10) @ image
| ^
20 | const [index, setIndex] = useState(0);
21 | const { decQty, incQty, qty, onAdd, setShowCart } = useStateContext();
22 | const handleBuyNow = () => {```"
```export const getStaticPaths = async () => {
const query = `*[_type == "product"]{
slug{
current
}
}`;
const products = await client.fetch(query);
const paths = products.map((product) => ({
params: {
slug: product.slug.current,
},
}));
return {
paths,
fallback: "blocking",
};
};
export const getStaticProps = async ({ params: { slug } }) => {
const query = `*[_type == "product" && slug.current == '${slug}'][0]`;
const productsQuery = '*[_type == "product"]';
const product = await client.fetch(query);
const products = await client.fetch(productsQuery);
return {
props: { products, product },
};
};
export default ProductDetails;
```"
"Thank you
When you click on 'Shop Now', it is supposed to open the cart directly."

**得分**: 1
不要解构你的属性，像这样：
```javascript
const { image, name, details, price } = product;
你应该像这样访问它们：
product?.image
这将帮助你避免错误，还可以有条件地检查特定属性是否存在。
英文:
Instead of de-structuring your properties like this
const { image, name, details, price } = product;
you should access them like this,
product?.image
This will help you avoid your error and also you can conditionally check if a particular property exists or not.
