AclNode::node() - Couldn't find %s node identified by "%s"

When I login to my site it gives me this exception and I don’t know why that’s happening.
How can I solve that issue?
This is the code for User.php:

<?php
declare(strict_types=1);

use Cake\ORM\TableRegistry;

I found out the solution, I was using the bindnode in userstable and it has to go in user entity, and I also was using the parameter $user as a class and it had to be an array, thank you for your help the same.

Hi @mdeanquin i also getting this error and I did same thing as mention bindNode method set into User Entity but i am getting still this error

can you explain me how to solve this problem
