[Jatapiaro]

I'm getting the following errors:

react-speech.js?49ba:562 Uncaught TypeError: Cannot read property 'object' of undefined
    at Object.eval (react-speech.js?49ba:562)
    at __webpack_require__ (react-speech.js?49ba:30)

    at eval (react-speech.js?49ba:10)
    at Object.<anonymous> (bundle.js:1)

And this is my code:

import React from 'react';
import HttpService from '../services/HttpService';
import WikipediaService from '../services/WikipediaService';
import Speech from 'react-speech';

export default class Wrapper extends React.Component {

    constructor(props) {
        super(props);
        this.httpService = new HttpService();
        this.wikipediaService = new WikipediaService(this.httpService);
    }

    componentDidMount() {
        this.wikipediaService.makeSearch()
            .then((res) => {
                console.log(res, 1);
            })
            .catch((err) => {
                console.log(err);
            });
    }

    render() {
        return (
            <div>
                <h1>This is the wrapper</h1>
                <Speech text="Welcome to react speech" />
            </div>
        );
    }

}
