Javascript on Google Sheets

So I created this script that retrieves the number of followers a playlist has on Spotify, and returns it to a cell in Google sheets. However, after working for over a year it is now broken and I can’t put my finger on why.

Here’s the script:

function SAMPLE(url) {
 const res = UrlFetchApp.fetch(url).getContentText();
 const v = res.match(/followers":({[sSw]+?})/);
 return v && v.length == 2 ? JSON.parse(v[1].trim()).total : "Value cannot be 

Then I have the URL in a cell and next a simple formula of =SAMPLE(A1)

Here’s the error I’m getting: SyntaxError: Unexpected end of JSON input (line 4).

Any help or guidance would be highly appreciated.

Thank you!
