Regarding showing error with withStyles ( version v1.0.0-beta.44 )

[Uma19]

Hello Team,
I am currently using latest material-ui beta 44 version and by doing below i am getting some error?
can you help me to explain why it is thrwing this error specially for position: 'relative'

export const styles = {
drawerPaper: {
position: 'relative'
},
};
export default withStyles(styles)(Sidebar);

by this because of position: relateive mentioned, withStyles(styles) is showing error as

Argument of type '(theme: Theme) => { root: {}; drawerPaper: { width: strin...' is not assignable to parameter of type
'Record<"root" | "expansionPanel" | "drawerPaper", CSSProperties> | StyleRulesCallback<"root

@Uma19 Please take a look at #10995
For now, you can do the following

type classList =
  | 'drawerPaper';

export default withStyles<classList>(styles)(Sidebar);

or

type classList =
  | 'drawerPaper';

const decorate = withStyles<classList>((theme) => ({
  drawerPaper: {
    position: 'relative'
  }
}));

export default decorate</*your Sidebar props interface here*/>(Sidebar);
