Table does not render (Yajra Datatables)

So, this is my controller:

use Yajra\DataTables\Facades\DataTables;
class CategoriasController extends Controller
{
    public function index()
    {
        return Datatables::collection(Categoria::all())->make(true);
    }
 [...]
}

this is my route:

Route::group(['middleware' => 'auth'], function () {
    Route::group(['middleware' => 'admin'], function () {   
        Route::prefix('admin')->namespace('Admin')->group(function () {
            Route::prefix('categorias')->group(function(){
                Route::get('/', 'CategoriasController@index')->name('curso.index');
[...]
             });
         });
     });
});

and this is my blade:

[...]
<div class="container">
    <table class="table border" id="myTable">
        <thead>
            <tr>
                <th>id</th>
                <th>Nome</th>
                <th>Criado</th>
                <th>Modificado</th>
            </tr>
        </thead>
    </table>
</div>
<script

<script src="https://cdn.datatables.net/1.10.19/js/jquery.dataTables.min.js"></script>
<script>
$(document).ready( function () {
    $('#myTable').DataTable({
        processing: true,
        serverSide: true,
        ajax: '{!! route('categoria.index') !!}',
        columns: [
                { data: 'id', name:'id'},
                { data: 'nome', name:'nome'},
                { data: 'created_at', name:'created_at'},
                { data: 'updated_at', name:'updated_at'},
            ]
    });
} );
</script>
[...]

And I got this as a return: Print

I'm using Laravel 5.8.19

composer.json

[...]
"require":{
        "yajra/laravel-datatables": "^1.5",
        "yajra/laravel-datatables-oracle": "~9.0"
}

So why is not a table rendering? Is it something I'm doing wrong? I ran the internet and I did not find a solution, I hope you will help me
