ref.map is not a function? - node.js

Question

this is my first post. Thank you all for the years, of assistance btw, I hope to pour in, as much as I've gotten from you guys/gals. Let's get started.
I have a Next.js / React-Redux application and here is my problem:
I'm attempting to update the Redux store, with JSON, that is returned from `fs.readFile' (the 'fs/promises' module:
//Product.js
function Product() {
const suggested_products = useSelector((state) => state.user.suggested_products) // json read from /api/products
const updateProducts = () => {
(JSON.parse(JSON.stringify(suggested_products)))?.map((product) => { // Compliler does not like this line
<div>
<input type='checkbox'>
<p> {product.category}</p>
<p>{product.service_name}</p>
</input
</div>
})
}
return (
if (userSelectedProduct) ? updateProducts() : <p>No data found</p>
}
//Form.js
import { useSWR } from 'swr'
const fetcher = (...args) => fetch(...args).then((res) => res.json());
function Form() {
const [url, setURL] = useState('');
const { data, error } = useSWR(url, fetcher);
<input
value={product}
onChange={
dispatch(updateCustomerCSP((JSON.parse(JSON.stringify(e.target.value)))));
setURL(`api/${product}/`); //Attempt to dynamically fetch data, from client side
dispatch(updateSuggestedProducts(data)); //Update data in store returned from client side fetching
}}
</input>
}
// pages/api/products
import fs from 'fs/promises';
export default function handler(req, res) {
const filePath = path.join(process.cwd(),`/data.js'); // /data.js contains JSON array [{"product-1": "value"}, {"product-2": "value"}], which is why I need to use map function.
try {
const fileData = fs.readFile(filePath);
const data = JSON.parse(JSON.stringify(fileData));
res.status(200).json(data);
} catch (err)
{
res.status(500).json({ error: 'Failed to load data' })
}
}
// This error throws ref.map is not a function from the Products.js component.
Here is the only info that I could find in regards to ref's in React.
Also, the JSON.parse and JSON.stringify wrappers, are to keep Redux happy with object going into the store. Thanks for reading community, looking forward to your input. Should any oneed more info, please let me know. Also, here is info in regards to refs, that I could find:

I figured it out. I actually had the input wrapped in a HOC, and the event handler wasn't properly registered to the input element itself., therefore failing to load in the array object into the store to use.
So be careful of that, when building your own components.
For instance,
function Component() {
function loadArrayInStore() {
loadInStore()
}
const MyButton = (props) => {
<input onChange={props.handler} // I had an inline handler here such as onChange={ (e)= { doNotLoadArrayInStoreAndDontWork()}
}
return (
<MyButton handler={loadArrayInStore} />
)
}
So be watchful, when creating HOC's :)
