Hi guys,
I have problem with react native

Uncaught Error: Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function but got: object

file App.js

import React, { Component } from 'react';
import { AppRegistry } from 'react-native';
import Articles from './src/components/Articles';

export default class myapp extends Component {

componentWillMount() {
    this.setState({
        articles : [
            {
                title : 'React Native',
                imageUrl : { uri : 'https://roocket.ir/public/image/2017/8/9/react-native.png'},
                body : 'react-native '
            },
            {
                title : 'webpack',
                imageUrl : { uri : 'https://roocket.ir/public/image/2017/7/27/webpack.jpg'},
                body : 'Webpack '
            },
            {
                title : 'Angular Cli',
                imageUrl : { uri : 'https://roocket.ir/public/image/2017/7/26/angular-1.png'},
                body : 'Angular cli '
            },
            {

                body : 'Laravel'
            },
            {
                title : 'Redux',
                imageUrl : { uri : 'https://roocket.ir/public/image/2017/8/9/react-native.png'},
                body : 'Redux '

            },
        ]
    })
}

render() {
    return (
        <Articles articles={this.state.articles} />
    )
}

}

AppRegistry.registerComponent('myapp', () => myapp);

Articles.js

                <Text numberOfLines={4} style={styles.body}>
                    { body }
                </Text>
            </View>
        </View>
        )

    _renderArticles(articles) {
        return articles.map((article, index) => <Article key={index} image={article.imageUrl} title=
        {article.title} body={article.body}/>
        )
    }

    render() {
