When adding slice : Error while saving your change - Click to retry

Hello everyone, I'm having this message "Error while saving your change - Click to retry" when I try to save a document. It only happens when one particular slice is called. This slice is empty, there is no primary or repeatable value attached to it. All the content of the slice is managed in my frontend.

When I try to save, the prismic API sends back a 400 error with this body :

Unable to save version:

What is weird is that I use the same exact slice in other pages and it used to work perfectly. It still is displaying the slice for the old pages, but I can't create a new one with this slice. Maybe the issue is on your side ? Let me know please !
