Problem description

During saving, or during autosave, I receive the following error. It doesn't seem to impact anything, and saved files work just fine.

Code of Conduct

kevenwyld commented 8 months ago

Looks like this was fixed upstream maybe https://github.com/shaise/FreeCAD_FastenersWB/issues/297 and https://github.com/FreeCAD/FreeCAD/issues/10460

We are merged with upstream on 2023.05.22 though so we don't have this fix yet.
