How can i get the name of images and use the images - reactjs

Question

In product page, I want to get all images path that are in a specific folder and send those to client side, so I can use them in client side by passing the paths to Image component of next js. I tried this when I was developing my app via running npm run dev and it was successful. Then I pushed the changes to my GitHub repository and vercel built my app again. Now, when I go to the product page, I get an error from the server. I tried some ways to fix this problem, but I couldn't fix that. For example, I tried changing my entered path in readdir, but the problem didn't fix. Here are my codes:
const getPagePhotosAndReview = async (productName) => {
const root = process.cwd();
let notFound = false;
const allDatas = await fs
.readdir(root + `/public/about-${productName}`, { encoding: "utf8" })
.then((files) => {
const allDatas = { pageImages: [], review: null };
files.forEach((value) => {
const image = value.split(".")[0];
const imageInfos = {
src: `/about-${productName}/${value}`,
alt: productName,
};
if (Number(image)) {
allDatas.pageImages.push(imageInfos);
}
});
return allDatas;
})
.catch((reason) => (notFound = true));
if (notFound) return 404;
await fs
.readFile(root + `/public/about-${productName}/review.txt`, {
encoding: "utf-8",
})
.then((value) => {
allDatas.review = value;
})
.catch((reason) => {
allDatas.review = null;
});
return allDatas;
};
export async function getServerSideProps(context) {
if (context.params.product.length > 3) {
return { notFound: true };
}
if (context.params.product.length < 3) {
const filters = {
kinds: originKinds[context.params.product[0]] || " ",
};
if (context.params.product[1]) filters.brands = context.params.product[1];
const products = getFilteredProducts(filters, true);
if (products.datas.length === 0) {
return {
notFound: true,
};
}
return {
props: {
products: { ...products },
},
};
}
if (context.params.product.length === 3) {
const filters = {
path: context.resolvedUrl,
};
const product = getFilteredProducts(filters, false);
if (product.length === 0) {
return {
notFound: true,
};
}
const splitedPath = product[0].path.split("/");
const pagePhotosAndReview = await getPagePhotosAndReview(
splitedPath[splitedPath.length - 1]
);
if (pagePhotosAndReview === 404) return { notFound: true };
product[0] = {
...product[0],
...pagePhotosAndReview,
};
product[0].addressArray = [
textOfPaths[context.params.product[0]],
textOfPaths[context.params.product[1]],
];
return {
props: {
product: product[0],
},
};
}
}
This is the base code and I tried some ways but couldn't fix the problem. So to fix this problem, I want to ask: how can I get the name of all images in a specific directory and then use those images in client side? And errors that I get: if I go to a page directly and without going to the home of the website, I get internal server error with code of 500 and when I go to a page of my website, and then I go to my product page, I get
Application error: a client-side exception has occurred (see the browser console for more information).
And I should say that I know I should remove public from paths when I want to load an image from public folder. I did it but I still get error.
