Caused by: 2ffd08e952

Short description of error
Please see the attached .blend file.

It uses Curve to Mesh to convert a curve into a mesh, and then uses Edge Path to Curves to convert the mesh back into curves.

When using Store Named Attribute this works as expected.

However, when using Capture Attribute it no longer works.

The Viewer shows that the anonymous attribute is correctly stored inside of the mesh, so it should work, but it doesn't.

Exact steps for others to reproduce the error

Open attached .blend file.
Select the Anonymous object. Notice that it does not work.
Select the Named object. Notice that it does work.

Hi, thanks for report. This is expected result. A Shortest Edge Paths node is evaluate attribute in curve, not on a mesh (result of Mesh to Curve node). You can avoid that by extra capturing End Vertex attribute on mesh until put that in to Shortest Edge Paths.
