Thumbnail missing, so how do I insert a different image for the missing image?

Okay, so for the second astronaut, there is no thumbnail image. Only the first astronaut loads. I can delete the <img src=${person.thumbnail.source}> from the generateHTML function and it'll work without pictures, but I was wondering if there's a way to skip over missing data instead of it crashing the rest of the page, or putting in a no picture image if there's no picture. How would I do this? I can't figure it out. My code looks like what Guil did, but here's a snapshot if you need it: https://w.trhou.se/lyufc4hqb4.

you could use an if statement checking if the response object has an image property or not, if not, show a default image.

I found that my "Andrew Morgan" astronaut was missing the "thumbnail". You can check the api resource to see "thumbnail is missing" : https://en.wikipedia.org/api/rest_v1/page/summary/Andrew_Morgan

So I did an if statement as Agustin suggested:

if(typeof(person.thumbnail) != 'undefined') { section.innerHTML = <img src=${person.thumbnail.source}> ; } section.innerHTML += <span>${person.craft}</span> <h2>${person.title}</h2> <p>${person.description}</p> <p>${person.extract}</p> ;
