I've followed the steps and found the error JSON.people when running the code and looking in the console.
How do I fix this?

Front End Web Development Techdegree Student 20,963 PointsHere's my code.
const astrosUrl = 'http://api.open-notify.org/astros.json'; const wikiUrl = 'https://en.wikipedia.org/api/rest_v1/page/summary/'; const peopleList = document.getElementById('people'); const btn = document.querySelector('button');
// Make an AJAX request function getJSON(url, callback) { const xhr = new XMLHttpRequest(); xhr.open('GET', url); xhr.onload = () => { if(xhr.status === 200) { let data = JSON.parse(xhr.responseText); return callback(data); } }; xhr.send(); }
// Generate the markup for each profile
function generateHTML(data) {
const section = document.createElement('section');
peopleList.appendChild(section);
// Check if request returns a 'standard' page from Wiki
if (data.type === 'standard') {
section.innerHTML =
<img src=${data.thumbnail.source}>
<h2>${data.title}</h2>
<p>${data.description}</p>
<p>${data.extract}</p>
;
} else {
section.innerHTML =
<img src="img/profile.jpg" alt="ocean clouds seen from space">
<h2>${data.title}</h2>
<p>Results unavailable for ${data.title}</p>
${data.extract_html}
;
}
}
btn.addEventListener('click', () => { getJSON(astrosUrl, (json) => { JSON.people.map(person => { getJSON(wikiUrl + person.name, generateHTML); }); }); });

And when posting non-workspace code, at least be sure to use Markdown formatting to preserve the code's appearance.

231,272 PointsEven without being able to try the code, "JSON" is a built-in object that has no "people" attribute. Did you perhaps mean to reference the parameter "json" (lower case) instead?
