htmlspecialchars() expects parameter 1 to be string, object given - php

Question

This is Controller. I named it CartController
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Gloudemans\Shoppingcart\Facades\Cart;
use App\Product;
class CartController extends Controller
{
public function index()
{
$cartItems=Cart::content();
return view('cart.index', compact('cartItems'));
}
public function edit($id)
{
$product=Product::find($id);
Cart::add($id,$product->name,'1',$product->price);
}
This is my welcome.blade.php. This is the page where I display all my Items.
<div class="row">
#forelse($books->chunk(4) as $chunk)
#foreach($chunk as $book)
<div class="column-prod">
<a href="{{url('view')}}">
<div class="card-prod">
<center><img src="{{url('images',$book->image)}}" style="width: 300px; height: 300px;"></center> </a>
<div class="container-prod">
<h2></h2>
<p class="title">{{$book->name}}</p>
<p class="price">₱ {{$book->price}}</p>
<p><i class="fas fa-cart-arrow-down"></i>Add to Cart</button></p>
<p><button class="button"><i class="fas fa-heart"></i> Add to Wishlist</button></p>
</div>
</div>
</div>
#endforeach
#empty
<h3> No Books </h3>
#endforelse
</div> <!--Div all end-->
This is the codes of my Cart Page. When the user click add to cart in the welcome page, his/her chosen items will be place in this page.
<h3> Cart Items </h3>
<!--TABLE NAMESSS-->
<table class="table table-hover">
<thead>
<tr>
<th scope="col">Image</th>
<th scope="col">Name</th>
<th scope="col">Price</th>
<th scope="col">Quantity</th>
</tr>
</thead>
<tbody>
#foreach($cartItems as $cartItem)
<li>{{$cartItem->name}}</li>
<tr>
<td>{{url('images',$cartItem->image)}}</td>
<td>{{$cartItem->name}}</td>
<td>{{$cartItem->price}}</td>
<td>{{$cartItem->qty}}</td>
</tr>
#endforeach
</tbody>
</table>
This is my route.
Route::get('/', function () {
return view('welcome')->with(['books' => \App\Product::all()]);
});
Route::get('/cart','ShopController#cart');
Route::get('/signin','ShopController#signin');
Route::resource('/cart','CartController');
Route::get('/wishlist','ShopController#wish');
Auth::routes();
Route::get('/logout', 'Auth\LoginController#logout');
Route::get('/home', 'HomeController#index');
Route::group(['prefix' => 'admin', 'middleware' => 'auth'], function(){
Route::get('/',function(){
return view('admin.index');
})->name('admin.index');
Route::resource('product','ProductsController');
Route::resource('category','CategoriesController');
});
Route::get('/categ', function(){
return view ('admin.category.categ_index');
});
I'm confused I don't know how to fix my error. This is the complete error that the system return.
"htmlspecialchars() expects parameter 1 to be string, object given (View: C:\xampp\htdocs\Shop\resources\views\welcome.blade.php)"
I hope you can help me in solving this. Your answers are very much appreciated.
