I've seen some info on this error but mostly related to fillets. In the attached file I'm just trying to do a thickness inward of 2.5 mm on faceds 33 and 17. This has worked in the past, though in the past I had built the additive loft portion first and worked from there.
How can I accomplish/fix this to end up with a hollow additive loft section with an inward thickness of 2.5mm.
Thank you.

Quick edit: Was reading some of the posts about this and fillets and it mentioned OCC version. I grabbed the newest appimage and tried that, same issue.
Also. I should have mentioned the thickness settings I was using are:
Face17
Face33
2.5 mm
Pipe
Arc
Make thickness inwards.
