Как решить проблему «Store does not have a valid reducer»?

Question

[kirillleogky]

Store does not have a valid reducer. Make sure the argument passed to combineReducers is an object whose values are reducers.

Структура проекта:


App.js

import React, { Component } from 'react'
import './App.css';
import Box from '@material-ui/core/Box';
import Grid from '@material-ui/core/Grid';
import Data from './data/data';
import TextField from '@material-ui/core/TextField';
import Button from '@material-ui/core/Button';
import { connect } from 'react-redux'


class App extends Component {
  render() {
    const { firstData, secondData } = this.props;
    return (
    <Box className="App">
      <h1 className="title">{firstData}{secondData}</h1>

    </Box>
  )
 };
}

const mapStateToProps = store => {
  return {
    firstData: store.firstData,
    secondData: store.secondData,
  }
}

export default connect(mapStateToProps)(App)

store/store.js

import {combineReducers, createStore} from 'redux';
import reducer from '../reducers'

export default createStore(combineReducers(reducer))

reducers/index.js

let firstData = {
  data: 'Fake'
};
let secondData = {
  data: 'Persons'
};

export default {firstData, secondData};

Редьюсерами должны быть функции, а не объекты
