I am getting below **error** which is for only `product controller` 

> 
> Route [dataProcessing] not defined.

In the `product` **controller** I have script as below 

```
public function index(){
    $Products = Product::all();
    return view('product-list', ['products' => $Products]); 
}

```

and in the **blade** I am just trying to echo the data 

```
{{ $products }}

```

and my **route** is as following 

```
Route::get('/product-list', 'ProductController@index');

```

Can someone kindly guide me why there is error even the script if so simple. Thank you so much.
