API post request not reaching the application - vue.js

Question

i'm new to laravel and i'm facing a painful problem.
I'm using Crinsane/LaravelShoppingcart in my ecommerce api and i'm trying to send a post request with axios in vuejs that adds a product to the cart by sending the product id and the quantity. The problem is the id and quantity are not reaching the application although i'm pretty sure i specified the correct route link in axios and i'm getting "No query results for model [App\Product]." which i assume means that the controller function that handles the request is working but the id is not being sent/transformed to the resource collection. I don't know if the problem is with the package i'm using or the code or something else.
this is axios request
addCart(item) {
axios
.post('/api/cart/add', item)
.then(response => (response.data.data))
.catch(error => console.log(error.response.data))
this is the route :
Route::post('cart/add', [
'uses' => 'ShoppingController#store',
'as' => 'cart.add'
]);
this is the cart collection
public function toArray($request)
{
return [
'id' => $this->id,
'qty' => $this->qty
];
}
this is the controller
public function store(){
$pdt = Product::findOrFail(request()->id);
$cart = Cart::add([
'id' => $pdt->id,
'name' => $pdt->name,
'qty' => request()->qty,
'price' => $pdt->price
]);
and this is the product model
class Product extends Model
{
protected $fillable = [
'name', 'description', 'image', 'category', 'quantity', 'price', 'sold','remaining','rating', 'bestSelling', 'featured'
];
}
Thank you in advance

The problem seems to be in your controller.
From the docs:
To obtain an instance of the current HTTP request via dependency injection, you should type-hint the Illuminate\Http\Request class on your controller method.
Try this:
public function store(Request, $request){
// Make sure the 'id' exists in the request
if ($request->get('id')) {
$pdt = Product::find($request->get('id'));
if ($request->get('qty')) {
$qty = $request->get('qty')
}
$cart = Cart::add([
'id' => $pdt->id,
'name' => $pdt->name,
'qty' => $qty,
'price' => $pdt->price
]);
}
Then, at the top of your controller, add:
use Illuminate\Http\Request;

So i found that it needed a json object to work and i had to put this code at the end of the store method :
return response()->json(['cart' => $cart], 201);
