Typing mapStateToProps React Redux

I am not able to type the “state” parameter of a mapStateToProps

If I just change state : any instead of state: AppState it works and no error.
But I would like to have a correct typing for my state parameter.

For now, I have this error on the mapStateToProps param of the connect()

No overload matches this call.
The last overload gave the following error.
Argument of type ‘(state: { quiz: IQuizInitialState; }) => StateProps’ is no assignable to parameter of type ‘MapStateToPropsParam’.
Cannot assign the type ‘(state: { quiz: IQuizInitialState; }) => StateProps’ to type ‘MapStateToPropsFactory’.
Parameters ‘state’ and ‘initialState’ are not compatible.
Property ‘quiz’ is missing in type ‘{}’ but required in type ‘{ quiz: IQuizInitialState; }’.ts(2769)

interface OwnProps {

}
interface StateProps {

}
interface DispatchProps {

}

type Props = OwnProps & StateProps & DispatchProps;


export class App extends Component<Props> {

  render() {
    return (
     <div>Hey</div>
    );
  }
}

const mapStateToProps = (state: AppState): StateProps => ({ 
})

const mapDispatchToProps = (dispatch: ThunkDispatch<{}, {}, AnyAction>): DispatchProps => {
    return {
    }
}


// The args 'mapStateToProps' generate the error
export default connect<StateProps,DispatchProps,OwnProps>(mapStateToProps, mapDispatchToProps)(App)

This is my rootReducer :

import { combineReducers } from 'redux';
import { QuizReducer } from './quiz';

const rootReducer = combineReducers({
    quiz: QuizReducer
});

export type AppState = ReturnType<typeof rootReducer>


export default rootReducer;

And the single reducer is :

import { TYPES } from '../actions/action-types';
import { IQuizListItem, Action } from '../models/index';
import { AnyAction } from 'redux';


export interface IQuizInitialState {
    quizListItem: IQuizListItem[]
}
const quizInitialState: IQuizInitialState = {
    quizListItem: []
}
export const QuizReducer = (state = quizInitialState, action: AnyAction): IQuizInitialState => {
    switch (action.type) {
        case TYPES.getQuizListItems:
            return {
                ...state,
                quizListItem: (action as Action<IQuizListItem[]>).payload
            }

        default:
            return state
    }
}

Thank you by advance guys !
