Hello everyone, by the way I am facing a problem while logging out of a user session

after having made the sales and I want to close the session I find myself with an error like:

​​Error closing session

An error occurred while trying to log out.

you will be redirected to the backend to log out manually

Please help me find a solution to this problem if anyone has any idea where this could be coming from.

NB: noted that when I connect with the administrator account and open the POS cash register I can close it without problem and the error does not appear
