Datatable warning Request Unknown parameter

I read a lot on this issue from datatable.net but couldn't figure out what the problem is. I also read from threads on this platform but couldn't find the solution to my specific problem. I am building an app with acl in laravel 5.6 and using datatable v 1.10.19 and jquery 3.2 Anytime I request data to be displayed by datatable, I get this alert(DataTables warning: table id=users - Requested unknown parameter '0' for row 0, column 0. For more information about this error, please see http://datatables.net/tn/4)

This is my view

<div class="content">
    <div class="container-fluid">
        <div class="row">
            <div class="col-lg-12">
                <table id="users" class="table table-strped table-dark">
                    <thead>
                      <tr>
                        <th scope="col">#</th>
                        <th scope="col">Name</th>
                        <th scope="col">Email</th>
                        <th scope="col">Action</th>
                      </tr>
                    </thead>
                    <tbody>

                    </tbody>
                  </table>           
            </div>
        </div>          
    </div><!-- /.container-fluid -->
</div>

And this is my controller

public function AllUser() {
    $user = User::all();
    return Datatables::of($user)
            ->addColumn('action', function($user) {

                '<a onclick="showData('.$user->id.')" class="btn btn-sm btn-success">Show</a>'.' '.
                '<a onclick="showData('.$user->id.')" class="btn btn-sm btn-info">Edit</a>'.' '.
                '<a onclick="showData('.$user->id.')" class="btn btn-sm btn-danger">Delete</a>';
            })->make(true);
}

My model is the normal user model that comes with laravel integrated with spartie

/**
 * The attributes that are mass assignable.
 *
 * @var array
 */
protected $fillable = [
    'name', 'email', 'password',
];

/**
 * The attributes that should be hidden for arrays.
 *
 * @var array
 */
protected $hidden = [
    'password', 'remember_token',
];

And this is my web route

Route::get('/all/user', 'UserController@AllUser')->name('allusers');
