@cmb69 Thank you 🙂 I just searched for the errors in the PR list and checked how we fixed this in the past, but apparently this was not enough. I'll read your article to see if that helps.

The error only occurs with MySQL 8.4, 8.3 is fine. That's how it's currently fixed for higher branches too. So I suggest we apply the same fix, and address the root issue in all branches once we upgrade to 8.4. But I'd ask somebody else to do that, as my knowledge on MySQL is fairly limited.

Fair enough.
