React Component cant acces Redux store - reactjs

Question

I have the following modules for my React app:
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import MainApp from './MainApp';
import reportWebVitals from './reportWebVitals';
ReactDOM.render(
<React.StrictMode>
<MainApp />
</React.StrictMode>,
document.getElementById('root')
);
MainApp.js
import React from 'react';
import App from './containers/app';
import './App.css';
import {ConnectedRouter} from 'connected-react-router'
import {Provider} from 'react-redux';
import {Route, Switch} from 'react-router-dom';
import configureStore, {history} from './store';
export const store = configureStore();
const MainApp = () =>
<Provider store={store}>
<ConnectedRouter history={history}>
<Switch>
<Route path="/" component={App}/>
</Switch>
</ConnectedRouter>
</Provider>;
export default App;
store/index.js
import {applyMiddleware, compose, createStore} from 'redux';
import reducers from '../reducers/index';
import {createBrowserHistory} from 'history'
import {routerMiddleware} from 'connected-react-router';
import createSagaMiddleware from 'redux-saga';
import rootSaga from '../sagas/index';
const history = createBrowserHistory();
const routeMiddleware = routerMiddleware(history);
const sagaMiddleware = createSagaMiddleware();
const middlewares = [sagaMiddleware, routeMiddleware];
const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;
export default function configureStore(initialState) {
const store = createStore(reducers(history), initialState,
composeEnhancers(applyMiddleware(...middlewares)));
sagaMiddleware.run(rootSaga);
if (module.hot) {
// Enable Webpack hot module replacement for reducers
module.hot.accept('../reducers/index', () => {
const nextRootReducer = require('../reducers/index');
store.replaceReducer(nextRootReducer);
});
}
return store;
}
export {history};
containers/dataviewer/index.js
import React from 'react';
import {connect} from 'react-redux';
import {
connectPath
} from '../../actions/Paths';
import Button from '#material-ui/core/Button';
import ButtonGroup from '#material-ui/core/ButtonGroup';
import TabularViewer from './TabularViewer';
import CollapsableViewer from './CollapsableViewer';
import ChartViewer from './ChartViewer';
class DataViewer extends React.Component {
constructor() {
super();
this.state = {
displayStyle: null
}
this.handleClick = this.handleClick.bind(this);
}
handleClick = (style) => {
this.setState({displayStyle: style})
}
DisplayControllers = () => {
return (
<ButtonGroup variant="text" color="primary" aria-label="outlined primary button group">
<Button color={this.state.displayStyle === 'tabular'? 'secondary': 'primary'} onClick={() => this.handleClick('tabular')}>Tabular</Button>
<Button color={this.state.displayStyle === 'collapsable'? 'secondary': 'primary'}onClick={() => this.handleClick('collapsable')}>Colapsable</Button>
<Button color={this.state.displayStyle === 'chart'? 'secondary': 'primary'} onClick={() => this.handleClick('chart')}>Gráfico</Button>
</ButtonGroup>
)
}
DisplayComponent = () => {
switch (this.state.displayStyle) {
case 'tabular':
return <TabularViewer />
case 'collapsable':
return <CollapsableViewer />
case 'chart':
return <ChartViewer />
default:
return <p>Seleccione un estilo de desplegado.</p>;
}
}
render() {
return (
<div>
<p>Data Viewer</p>
<this.DisplayControllers />
<this.DisplayComponent />
</div>
)
}
}
const mapStateToProps = ({paths}) => {
const {connection, path, data} = paths;
return {
connection,
path,
data
}
}
export default connect(mapStateToProps, {connectPath})(DataViewer)
Te problem is that I get the following error when the component is mounted:
Error: Could not find "store" in the context of "Connect(DataViewer)". Either wrap the root component in a <Provider>, or pass a custom React context provider to <Provider> and the corresponding React context consumer to Connect(DataViewer) in connect options.
I can't see what I am missing.
EDIT
containers/app.js
import React from 'react';
import DataViewer from './DataViewer';
class App extends React.Component {
render() {
return (
<div className="App">
<header className="App-header">
<DataViewer
database_host="127.0.0.1'"
database_port="5432"
database_name="TCDigital"
database_user="postgres"
database_password="xxxx"
path="Ventas"
displayStyle="collapsable"
/>
</header>
</div>
);
}
}
export default App;
