Instagram changed something on their backend and the project returns an 'invalid JSON' error on line 159

Uncaught SyntaxError: Unexpected end of JSON input at JSON.parse (<anonymous>) at XMLHttpRequest.xhr.onreadystatechange (chrome-extension://pblgjchnlklkdkhcafceklibimpdfgbe/js/instagram.js:159)

The extension is trying to reach and parse https://www.instagram.com/<username>/?max_id=1 .

Ok after using this extension I must say that it needs to be able to download all the images in a zip file because my browser has been shut down 3 times after trying to download 95 photos which open 95 download windows and stop responding.

Thanks

It generates thousands of dialogs if used without zipping which renders it ineffective as a mass downloader. I see the error on line 159, but am unsure of what data/structure the extension is expecting/designed to use and thus cannot create a solution. I saw a similar version of this issue was closed but have seen no solution. Is this unfixable/abandoned?
