Cannot wrap honeycomb array around tube with thickness and fillde face

[Nerol-Windwaker]

Error: "Cannot compute Inventor representation for the shape of round_WRAPPED_HONEYCOMB_ARRAY#Sketch_On_Surface: Geom2d_TrimmedCurve::U1 == U2"

pattern looks like this

Broken face looks like this

With old curveWB version all works fine

Program versions: FreeCAD 0.21.2 Curves 0.6.42

I'm getting the same issue trying to do the same kind of part. As soon as I add a thickness to the Sketch-on-surface, things fall apart. If I do the full wrap of 360 or so objects, we fail with "Invalid initial face" and " Cannot compute Inventor representation for the shape of holder_model_v1#Sketch_On_Surface: Geom2d_TrimmedCurve::U1 == U2". If I just do a few of them, I can get it to not error, but it's clear something has gone wrong in creating the faces.

Going back to older versions -- 0.6.35 still has the issue 0.6.34 has a flavor of the issue. The face is simpler (a diamond) and doesn't extrude 0.6.33 does not have the issue - fine 0.6.32 does not have the issue - fine 0.6.30 does not have the issue - fine
