Exception "Standard_NoSuchObject: BRep_Tool:: no parameter on edge" is raised when making offset of the sweep
Description
It's just a question. I have no idea what this exception is supposed to mean.

The exception "Standard_NoSuchObject: BRep_Tool:: no parameter on edge" is raised from the method BRep_Tool::Parameter when the input vertex does not belong to the input edge.
In this context it can mean that there is an issue in the input data or the algorithm that leads to incorrect call of this method.

Dear Author, please turn this issue to "reviewed" state if you are satisfied with the answer.
In order to request the healing of the offset algorithm it is needed to update bug description and parameters.
This problem is hard to reproduce. Out of nowhere it suddenly gave the correct the result. The output of the sweep changed somehow. The tesselation and the vprops look the same. But a diff of the breps shows differences.
The most obvious one is that the alternative input shape has "Curve2ds 22" whereas the original has "Curve2ds 0" and Surfaces 7 compared to Surfaces 0
So I'm still not sure if the sweep is to blame or the offset.

As the initial shape Attachment 1 (BREP) is formally valid (by checkshape) and offset raises exception, it is needed initially to try to analyze the behavior of offset.
