How to map API with multiple objects [Spree API V2 & ReactJS]

I'm building a webshop, using ReactJS for the front-end and Spree (Ruby) for the back-end.

Spree offers an API solution to connect the front-end and the back-end with one and other.

I'm trying to display products with product images, but Spree's API is setup in a specific way that product images and products aren't in the same object.

The API response is:

 {
    (holds products)data: [],
    (Holds product images)included:[],
 }

My goal is to create an ul with the product information and product image displayed.

I've tried to map my API link which

           this.state.arrays.map((product) => 
              product.data
            )

Which responds with the data object, but I cant for example do product.data.name because it returns an undefined response

Product Index page

import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import PropTypes from "prop-types";
import ProductsList from "./products/ProductsList";
import axios from 'axios';



const REACT_VERSION = React.version;
const include = '?include=images';
const API = 'https://stern-telecom-react-salman15.c9users.io/api/v2/storefront/products' + include;

const styles = {
  card: {
    maxWidth: 345,
  },
  media: {
    height: 140,
  },
};

class Index extends React.Component {
    constructor(props){
        super(props);
        this.state = {
            products: [],
            productsData: {},
            isLoading: false,
            error: null,
    };
  }
  componentDidMount() {
    this.setState({ isLoading: true });
    axios.get(API)
      .then(result => this.setState({
        products: result.data.data,
        productsData: result.data,
        isLoading: false,
      }))
      .catch(error => this.setState({
        error,
        isLoading: false
      }));
      // console.log(
      //   'productsData', 
      //   this.state.productsData

      //   )
  }
  render() {
    const { products, productsData,isLoading, error } = this.state;

    if (error) {
      return <p>{error.message}</p>;
    }
     if (isLoading) {
      return <p>Loading ...</p>;
    }
    return (
      <React.Fragment>
          <h1>React version: {REACT_VERSION}</h1>
          <ProductsList products={this.state.productsData}/>
      </React.Fragment>
    );
  }
}

ProductsList.propTypes = {
  greeting: PropTypes.string
};

export default Index

ProductList Page

import React from "react"
import PropTypes from "prop-types"

import { withStyles } from '@material-ui/core/styles';
import Card from '@material-ui/core/Card';
import CardActionArea from '@material-ui/core/CardActionArea';
import CardActions from '@material-ui/core/CardActions';
import CardContent from '@material-ui/core/CardContent';
import CardMedia from '@material-ui/core/CardMedia';
import Button from '@material-ui/core/Button';
import Typography from '@material-ui/core/Typography';

const url = "https://stern-telecom-react-salman15.c9users.io"

class ProductsList extends React.Component {
  constructor(props) {
    super(props);
    const { products } = this.props;
    const arrays = Object.values( {products} );
    this.state = {
      products,
      arrays
    };
  }
  render () {
    return (
      <React.Fragment>
        <ul>
          <p>Shop Products</p>
          {
          // console.log(
          //   'PL',
            // this.state.arrays.map((product) => 
            //   product.data
            // )
          // )
          this.state.arrays.map(product =>
            <li key={product.objectID}>
            <Card>
                  <CardActionArea>
                    <CardMedia
                      image= {url + ''}
                      title={product.data.attributes.name}
                    />
                    <CardContent>
                      <Typography gutterBottom variant="h5" component="h2">
                       {product.data.attributes.name}
                      </Typography>
                      <Typography component="p">
                        {product.data.attributes.description}
                      </Typography>
                    </CardContent>
                  </CardActionArea>
                  <CardActions>
                    <Button size="small" color="primary">
                     {product.data.attributes.display_price} 
                    </Button>
                    <Button size="small" color="primary">
                      add to cart
                    </Button>
                  </CardActions>
                </Card>
            </li>
            )
          }
        </ul>
      </React.Fragment>
    );
  }
}

ProductsList.propTypes = {
  greeting: PropTypes.string
};
export default ProductsList

What I expect to get as Result is product information and image
