Articulate Storyline: Export to Google Drive

Hi there!

I've been using this method to send variables to Google Sheets for several months and it worked very well. But strangely, since we migrated our website to a new host (which uses nginx servers), it doesn't work anymore. They confirm to me on their side that no external communication  blocked, but ultimately, the information doesn't go to Sheets anymore.

Here's what my browser console says :
---From the first slide---
user.js:81 Uncaught SyntaxError: Invalid or unexpected token
/favicon.ico:1 Failed to load resource: the server responded with a status of 404 ()

---From the end / trigger slide---
app.min.js:3 actionator::exeJavaScript - this.execUserJs is not a function
