Geometry Intersects, NurbsCurves and Floor By Outline Errors

Good morning everybodies,
Indeed, could you share your file or a JPG!
Actually I have the same issue with the same node so it could be very interesting for me to see how you solved it!
:wink:
My node is telling me : warning :Floor.ByOutlineTypeAndLevel operation failed.
The multiplicities of other interior knots must be at most degree - 2.
Parameter name: knots
Thank you very much!
