throw Error :The datasource configuration "" was not found.

<?php
namespace App\Model\Table;
use Cake\Event\Event;
use Cake\ORM\Table;
use Cake\ORM\Entity;
use Cake\Validation\Validator;
class MenusTable extends Table
{
    public function initialize(array $config)
    {
        $this->addBehavior('Tree');
        $this->addBehavior('Acl.Acl',['type' => 'controlled','alias'=>true]);
    }

My datasource configureation is fine.

Acl bootstrap.php

use Cake\Core\Configure;

if (!Configure::read('Acl.classname')) {
    Configure::write('Acl.classname', 'DbAcl');
}
if (!Configure::read('Acl.database')) {
    Configure::write('Acl.database', 'default');
}
