The error is straight forward. You haven't gotten any objects of $category_name variable and you're trying to access to the value of the name property. Which is not defined because there's no object.

Add a simple condition to fix it like this

public function viewProducts(){
  $products = Product::get();
  $products = json_decode(json_encode($products));

  foreach($products as $key => $val){
    $category_name = Category::where(['id'=>$val->category_id])->first();
      if($category_name != null){
        $products[$key]->category_name= $category_name->name;
      }
    }
  echo "<pre>";print_r($products);die;

  return view('admin.products.view_products')->with(compact('products'));
}

To send data to your blade:

# Controller:
$data['category_name'] = $category_name;
$data['products'] = $products;
->withKeyName($data);

# Blade:
{{ $KeyName['category_name'] }}
{{ $KeyName['products'] }}
