Splitting Goole-Play-Scraper Results - node.js

Question

I have a React front-end with a Node back-end, and all I'm trying to do is scrape some data from the Google Play Store using Facundo Olano's Google-Play-Scraper.
This is my React front-end...
import React, {Component} from 'react';
import './App.css';
export default class App extends Component {
state = {
title: '',
review: ''
};
componentDidMount() {
this.callApi()
.then(res => this.setState({
title: res.title,
review: res.review
}))
.catch(err => console.log('Error: ', err));
}
callApi = async () => {
const response = await fetch('/gPlay');
const body = await response.json();
if (response.status !== 200) {
throw Error(body.message);
}
return body;
};
render() {
console.log("==================== app log ====================");
console.log("State: ", this.state);
return (
<div className="App">
<p>Title: {this.state.title}.</p>
<p>Review: {this.state.review}.</p>
</div>
);
}
}
This is my Node back-end...
[const express = require('express');
const app = express();
const port = process.env.PORT||5000;
const gPlay = require('google-play-scraper');
const appToScrape = 'com.mojang.minecraftpe';
app.get('/gPlay', (req, res) => {
const gPlayResults = gPlay.app({appId: appToScrape});
console.log('==================== server log ====================');
gPlayResults.then(console.log);
res.send({
title: 'title',
review: 'review',
});
});
app.listen(port, () => console.log(`Listening on port: ${port}`));
This is a small snippet of the results i'm getting...
{
price: 6.99,
free: false,
currency: 'USD',
priceText: '$6.99',
offersIAP: true,
size: 'Varies with device'
}
I'm getting the full results as per the doc's, but I need to be able to split the returned object up to be able to send bits of it back to the front-end, but I can't for the life of me get it to work.
I thought I could just simply do something like gPlayResults.price and have 6.99 returned, but all that comes back is undefined.
Please can someone help, I must be missing something as it surely can't be that hard!?
Thanks xxx

Ok, I worked it out! :)
For anyone who's interested, gPlayResults is being assigned a Promise and not the object I was expecting.
I made a callback using .then and was able to use the result I needed to send a usable object back to the front end.
const express = require('express');
const app = express();
const port = process.env.PORT || 5000;
const googlePlayApp = require('google-play-scraper');
const appToScrape = 'com.mojang.minecraftpe';
app.get('/gPlay', (req, res) => {
console.log('==================== /gPlay ====================');
const gPlayResults = googlePlayApp.app({appId: appToScrape});
gPlayResults.then(function(result) {
res.send({
appObject: result
})
});
});
app.listen(port, () => console.log(`Listening on port: ${port}`));
On to the next problem...
