When I run my code, the console throws an error for the original code the teacher provided. It says Uncaught TypeError: Cannot read property 'source' of undefined at generateHTML (callbacks.js:24) at XMLHttpRequest.xhr.onload (callbacks.js:13)

// Generate the markup for each profile
function generateHTML(data) {
const img_src = (data.thumbnail && data.thumbnail.source) ? data.thumbnail.source : '';
const section = document.createElement('section');
peopleList.appendChild(section);
section.innerHTML = `
<img src=${img_src}>
<h2>${data.title}</h2>
<p>${data.description}</p>
<p>${data.extract}</p>
`;
}
