Redux combineReducer using Flow and flow-typed for redux

I've got two reducers in the app combined with combine reducer (reducer.js).

import { combineReducers } from 'redux';

export const reducers = {
    search: searchReducer,
    table: tableReducer
};

export const reducer = combineReducer(reducers);

Also I have a snippet to automatically parse store types from reducers (from this Medium post) using Store from flow-typed redux_v3.x.x.js

import { reducers } from './reducer';

type Reducers = typeof reducers;

type $ExtractFunctionReturn = <V>(v: (...args: any) => V) => V;
export type State = $ObjMap<Reducers, $ExtractFunctionReturn>;

export type Store = ReduxStore<State, Actions>;

And I got an error from flow-typed CombinedReducer that it can't find reducers (search and table).

src/types.js:65
65: export type Store = ReduxStore<State, Actions>;
                                ^^^^^ property `search`. Property not 
found in
54:   declare function combineReducers<O: Object, A>(reducers: O): 
CombinedReducer<$ObjMap<O, <S>(r: Reducer<S, any>) => S>, A>;

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ object type. See lib: flow-
typed/npm/redux_v3.x.x.js:54

src/types.js:65
65: export type Store = ReduxStore<State, Actions>;
                                ^^^^^ property `table`. Property not 
found in
54:   declare function combineReducers<O: Object, A>(reducers: O): 
CombinedReducer<$ObjMap<O, <S>(r: Reducer<S, any>) => S>, A>;

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ object type. See lib: flow-
typed/npm/redux_v3.x.x.js:54

How to solve that error and make my Store working correct with Flow?

Before that error I got another one

Flow: object map. This type is incompatible with union: Intersection 
type | undefined.
flow-typed/redux_v3.x.x.js
30: declare type CombinedReducer<S, A> = (state: $Shape<S> & {} | void

And I have added Object type to declare type CombinedReducer (actually I don't think I should edit flow-typed and in the Medium example there is no such an error):

declare type CombinedReducer<S, A> = (state: $Shape<S> & {} | Object | void

I suppose these errors can be caused by the same thing.
