Material-UI error on Nav Drawer classes customization

[Marouann]

Hello,

I am customizing the Drawer of the Nav component. I'am doing simply :

import { Nav } from 'mui-layout';

<Nav
    classes={{
        container: navClasses.container,
        paper: navClasses.paper,
        paperAnchorDockedLeft: navClasses.paperAnchorDockedLeft,
    }}
>

This is working fine since Nav is doing :

<Drawer
        {...props}
        className={`${className} ${classes.root}`}
        open={opened}
        onClose={() => setOpened(false)}
        variant={navVariant}
        anchor={navAnchor}
>

My only problem is : Material-UI is printing me some errors in console :

Material-UI: the key `container` provided to the classes prop is not implemented in ForwardRef(Drawer).
You can only override one of the following: root,docked,paper,paperAnchorLeft,paperAnchorRight,paperAnchorTop,paperAnchorBottom,paperAnchorDockedLeft,paperAnchorDockedTop,paperAnchorDockedRight,paperAnchorDockedBottom,modal

Or

Material-UI: the key `container` provided to the classes prop is not implemented in ForwardRef(Drawer).
You can only override one of the following: root,docked,paper,paperAnchorLeft,paperAnchorRight,paperAnchorTop,paperAnchorBottom,paperAnchorDockedLeft,paperAnchorDockedTop,paperAnchorDockedRight,paperAnchorDockedBottom,modal. 

Am I doing something wrong ?
