  TypeError: can't multiply sequence by non-int of type 'float'

I haven't tried to narrow this down to a certain table or image (which I assume is the reason, because otherwise other documents with the same general styling convert just fine), but could do so if needed (with some effort).
This is weasyprint==62.3 on Ubuntu 22.04.

I can't share them directly, but I'll try to produce a minimized example.

A minimized example would be great. Else you can send them by email.

Thanks a lot.

That’s related to flex layout, we’ll check that everything is OK when the flex module is rewritten.
